Overview
What the Master of Science in Photonics is
The program covers the essential aspects of the field in enough detail for graduates to practice photonics professionally: nonlinear optics, optical materials, optical devices and components, and optical communications systems.
Your core coursework is organized into five course areas, and you complete one course from each. That gives every student a shared footing in photonics and nonlinear optics, electricity and magnetism, semiconductor devices and solids, quantum mechanics, and the optical properties of materials. Courses come from electrical and computer engineering, physics and materials science and engineering.
Electives let you lean toward electromagnetics, photovoltaics, electron microscopy and diffraction, or computational and mathematical physics. If you want hands-on research experience, up to 6 credits can go to a thesis or an independent study.
A 30-credit degree, typically 1.5–2 years of full-time study, delivered on campus.

Curriculum
What you study
The degree requires 30 graduate credits: 15 credits of required photonics core courses, 9 to 11 credits of photonics electives, and 4 to 6 credits of electives or research.
- Photonics core, 15 credits. Complete five courses, one from each of five course areas, each with a B- or better. Area 1 is Photonics and Nonlinear Optics (PHY 355). Area 2 is Fundamentals of Photonics (ECE 448) or Electricity and Magnetism (PHY 421). Area 3 is Physics of Semiconductor Devices (ECE 451) or Physics of Solids (PHY 363). Area 4 is Applied Quantum Mechanics for Engineers (ECE 450) or Quantum Mechanics I (PHY 423). Area 5 is Optical Properties of Solids (PHY 396) or Optical Properties of Materials (MAT 416).
- Photonics electives, 9 to 11 credits. Take at least three courses from this list: Advanced Electromagnetics (ECE 402), Introduction to Photovoltaic Energy Systems (ECE 422), Electron Microscopy and Microanalysis (MAT 334), Advanced Scanning Electron Microscopy (MAT 427), Crystallography and Diffraction (MAT 333), Introduction to Computational Physics (PHY 380), Quantum Mechanics II (PHY 424), Methods of Mathematical Physics (PHY 428), and Atomic and Molecular Physics (PHY 446).
- Electives or research, 4 to 6 credits. At least 4 credits at the 300 and 400 level from within ECE, in courses not used for the core or the photonics electives, or advisor-approved electives outside ECE. This can include up to 6 credits of thesis (ECE 490) or up to 6 credits of independent study (ECE 492), and up to 6 credits of 200-level courses outside ECE with advisor approval.
- Course-level rules. At least 24 credits must be at the 300 and 400 level, with 18 of them at the 400 level, and research or thesis registration can count toward the 400-level requirement. At least 18 credits must be in the major field, with 15 of them at the 400 level. You need a B- or better in at least 18 credits of your program and in all 300-level courses in the major field, and courses graded C- or better count toward the degree. ECE 300 and courses with an ESLP or EAPC subject code do not count.
