Optical Sciences (PHD) 
Program Description
The Ph.D. in Optical Sciences program prepares students for extraordinary opportunities in a fast-changing, high-tech world.
 
Graduates should expect to find unusually comprehensive career options available to them: They may lead, found, or make vital contributions to national or international academic institutions, research facilities or companies, or they may write revolutionary texts, advise U.S. presidents and agencies, make breakthroughs in fundamental science, contribute to NASA’s space program, develop critical defense technologies, innovate unprecedented advances in communications and entertainment, or devise lifesaving medical diagnostics.
 
Ph.D. students begin by taking a series of core courses designed to provide them with a solid background in optics. As they progress, they gain firm foundations in math and physics, statistics, electromagnetic waves, geometrical optics, quantum optics, and solid-state optics. The balance of coursework is flexible, and students will have the opportunity to explore all of the possibilities that interest them.
 
The centerpiece of a Ph.D. program is research leading to a dissertation, where students demonstrate a capacity for research resulting in an original contribution to scientific knowledge or engineering in Optical Sciences. As students progress, mentored by OSC faculty members, they will pass a series of oral and written exams culminating in the final Ph.D. dissertation defense.

Degree Specifics

Degree Requirements

Time Limit

  • Degrees must be completed within five years of the student’s completion of his or her oral comprehensive examination. The Graduate College will grant extensions only in exceptional circumstances and may require students to retake the comprehensive examination. The average time to degree for Ph.D. students is 5.5 years.

Plan of Study

Working together with their major professor, each student develops a written study plan that will specify the balance between coursework and dissertation units for their Ph.D. degree. This plan must be filed with the department at the time the written portion of the comprehensive examination is taken.

Examinations

Qualifying Exam

This exam is administered in the form of an interview with a faculty member during the student's first semester in residence.

Comprehensive Exam

The comprehensive examination consists of a written examination followed by an oral examination. The written portion is administered near the beginning of the fall and spring semesters, and consists of two 3.5 hour exams covering material in the core courses. Upon passing the written examination, an oral examination is given later in the same semester. The examining committee consists of the student's dissertation adviser plus three or four additional professors chosen from other areas of optics. The comprehensive examination may only be taken by Ph.D. students who have passed a minimum of 32 units of graduate coursework (including transfer units from other institutions, but not including dissertation units).  Most students take this exam during their fifth or sixth semester in residence, although it may be taken earlier or later, depending on the circumstances.

Dissertation Proposal

The dissertation proposal examination is an oral examination administered by the student’s dissertation committee. This committee consists of the student's dissertation advisor plus two additional members nominated by the student in consultation with his or her advisor and approved by the associate dean for academic programs. Its purpose is to determine if the coursework and other studies undertaken by the student in their area of specialization has adequately prepared them for their proposed dissertation research. This examination is taken after the student has passed the written and oral comprehensive examinations and substantially completed their coursework. It typically lasts one to two hours. For most students, this will be near the end of their third year of full-time study, but it may not be later than one year prior to the completion of the dissertation and/or the student’s final oral dissertation defense. It is preferable that this examination be taken as near to the beginning of a student’s dissertation research as possible.

Oral Defense Exam

The committee appointment form must be submitted to the Graduate Degree Certification Office before scheduling the final oral defense examination. It should be submitted as soon as the student completes the written and oral comprehensive exam or the dissertation proposal exam. 

The oral defense examination is commonly referred to as a defense of the dissertation, although general questioning related to the field of optical sciences may naturally develop during the course of the exam. It is administered by the student’s dissertation committee. The dissertation committee is comprised of at least three tenured or tenure-track faculty. If appropriate to the student’s dissertation research, one non-tenured or -tenure-track faculty may be approved by the Degree Certification Office. The exam time and place must be scheduled about two weeks in advance. It is open to the public.

Ethics Courses

University of Arizona graduate-level ethics courses may count toward the M.S. in Optical Sciences and Ph.D. in Optical Sciences programs at the College of Optical Sciences, with approval from the associate dean for academic programs.

Transfer Courses

With approval of the associate dean, graduate work completed at another graduate-accredited institution may be transferred, provided these courses received a grade of A or B, are comparable to a UA course and were not used toward an undergraduate degree. Students must complete an evaluation of transfer credit form for approval by the associate dean in their first semester.

Waivers to these requirements may be granted by the associate dean for academic programs when determined to be in the best interest of the student and the college. The student's dissertation director will often be consulted prior to granting a waiver. All such waivers must be in accordance with the policies of the University of Arizona.

There is no specified maximum number of units a student may transfer; it depends on one’s background and chosen study program. Subject to department approval, as many as 12 to 18 units may be transferred (usually from math, physics or engineering courses).

Approved transfer courses are entered in the transfer section on the plan of study.

Coursework

The number of units of graduate credit required for the Ph.D. in Optical Sciences is not specified explicitly; the requirement is for the equivalent of six semesters of full-time study. A minimum of 18 units of dissertation and 54 units of coursework is required.

OPTI 599: Independent Study units must meet the Graduate College policy and be approved by the associate dean for academic programs. Generally, six units of OPTI 599 are approved. Please note that only two nontechnical courses may count toward the Ph.D. degree requirements.

With the approval of the student's dissertation director, the required number of units may be reduced to 45. There are no exceptions to this minimum. The default requirement is not 45 course units. Note: The 45 units of coursework exception may be appropriate for a minority of students whose field of research requires fewer advanced courses and greater time for research.

Also with the approval of the dissertation director, a student may list a single C-graded course on their plan of study, although the student and his or her dissertation director should carefully consider the value of retaking a course with a C grade.

54 unit and C-grade waiver form must be signed and submitted along with the student's doctoral plan of study.

OPTI 597B does not count toward fulfilling the Ph.D. program course requirements.

Core Curriculum

A total of eight courses from the following lists are needed to fulfill a student's core course requirements. Substitutions or waivers for core courses are not permitted other than in exceptional circumstances. A request for a course substitution or waiver must be approved first by the Associate Dean for Academic Programs and may require review by the Graduate Curriculum Committee. Students requesting substitutions or waivers should submit a one-page petition explaining the request and justification to Academic Programs prior to taking the written comprehensive exam. Requests will not be considered after a student completes their comprehensive exams. Transfer credit that is equivalent to core course requirements must be pre-approved by the Associate Dean for Academic Programs.

*OPTI 544 and OPTI 570A assume previous academic experience in physics, particularly undergraduate-level quantum mechanics. The PQO track B is recommended primarily for students who wish to pursue quantum optics, physics-oriented photonics and solid-state optics research.

Laboratory Requirements

All students must include at least two introductory optics laboratory courses as part of their plan. These classes should provide hands-on experiences to help the students learn the fundamentals that are taught in the core lecture classes. While two lab courses are required, additional laboratory courses are strongly recommended. The classes currently offered that satisfy this laboratory requirement are:

 
Minor Requirements

Minor

Most students both major and minor in optical sciences; however it is also possible to minor in another department. Students taking courses outside the College of Optical Sciences for credit toward a minor in that department must meet with the graduate advisor of the other department to ensure all requirements for their minor are met.

Students interested in the quantum optics track of optical sciences may particularly wish to consider a minor in physics. Nevertheless, students are welcome to take courses in other departments even if they intend to minor in optical sciences  — we are flexible enough that virtually all of the courses in an related minor field may be taken without formally selecting it as a minor.  The associate dean for academic programs can advise you if there is any question about whether a specific course is suitable for your degree program

Students majoring in other disciplines may elect to minor in optical sciences by completing 12 units of approved College of Optical Sciences course work with a grade of B or higher. One College of Optical Sciences faculty member is required to serve on the minor student's oral comprehensive exam committee (faculty members with a joint appointment in the student’s major department are highly recommended). Study plans for students wishing to minor in optical sciences must be approved in advance by the associate dean for academic programs. In general, approval will be only given to plans in which at least nine of the 12 units are courses for which the College of Optical Sciences is the home department.
