On-campus only


ECE 30100 and (ECE 20008 or ECE 20800) and (ECE 30411 or ECE 31100) and ECE 30414 [may be taken concurrently]

Requisites by Topic:

Uniform plane waves, reflection and refraction of plane waves, rudimentary differential equations and matrix algebra, basic concepts in electric circuits and in semiconductor devices, basic concepts of electromagnetism, Maxwell's equations. This class is designed for advanced undergraduate students.

Catalog Description:

This laboratory course exercises in lasers, modulation of laser beams, fiber components and systems. It covers some simple optical measurements like Power and beam spot measurement of Gaussian beams. Students learn about lens-pinhole spatial filters and beam expanders. Fourier transform, convolution and correlation are covered. Characteristics of LEDs and ILDs are shown. Students become familiar with optical fibers related experiments like Fiber-optic microbend intensity sensors, Electrooptic modulation, Fiber optic Mach-Zehnder interferometer etc. Students also learn how to build laser systems based on the knowledge acquired from previous labs and with some simple set up. Finally there is a final project where students can design a practical optical instrument based on their knowledge from the lab.
