ECE 41200 - Introduction to Engineering Optics

Lecture Hours: 3 Credits: 3

Professional Attributes
EE Elective

Normally Offered: Each Spring

Requisites:
ECE 31100 and ECE 30100 [may be taken concurrently].

Requisites by Topic:
Basic concepts of electromagnetism such as Maxwell's equations, uniform plane waves and reflection and refraction of plane waves

Catalog Description:
The control and characteristics of optical radiation are covered. Applications to optical instrumentation, thin films, holography and polarizing optics are discussed. Major topics: Geometrical Optics: Lenses, prisms; Huygens' principle, Fermat principle; Rays; Incoherent light. Physical Optics: Gratings, interferometers, diffraction elements, polarizers; Huygens-Fresnel principle, Maxwell's equations; Waves; Field vectors; Amplitude and phase, Coherent light. Law of reflection and refraction.

Course Objectives:
The student should be able to: Analyze simple optical systems consisting of lenses, stops, reflectors and prisms, determine and use principal points and focal points, and calculate and describe optical aberrations. Analyze and design polarization systems, including wave plates, optically active materials, and Faraday rotators. Analyze interferometers such as the Michelson, Fabry-Perot, thin film and double-slit. Analyze Fraunhofer and Fresnel diffraction patterns, design simple spatial filters, determine and use transfer functions of optical systems, and apply these principles to holography.

Supplementary Information:
Will be offered spring only semesters effective fall 2016. Students are also suggested to consider taking the lab course ECE 41300 together with ECE 41200.

Required Text(s):
  1. Fundamentals of Photonics, E.A. Saleh & Malvin Carl Teich, Wiley-Interscience, 2007, ISBN No. 9780471358329.

Recommended Text(s): None.

Learning Objectives:

A student who successfully fulfills the course requirements will have demonstrated:
  1. An ability to analyze simple optical systems (dielectric slabs, thin lenses, reflectors). [a,k]
  2. An ability to model Gaussian beams and the transformation of beams. [a,k]
  3. An ability to analyze and design polarization systems, including polarizers and wave plates. [a,c,k]
  4. A knowledge of optical interferometers and the operations of interferometers such as the Michelson, Fabry-Perot and double-slit . [a,k]
  5. An ability to analyze diffraction patterns. [a,k]
Assessment Method for Learning Objectives: You will have more than one opportunity to satisfy each of the Course Outcomes. The primary means will be through homeworks, the two tests during the semester and one final exam. We will write questions for each test/exam around each of the Course Outcomes. You will satisfy each Course Outcome when your score for the test question(s) equals or exceeds a value we specify as representing a minimal competency. If you fail to meet this level of minimal competency on a specific Course Outcome, you will have a second chance through a retest or other additional assignment.
