OVERVIEW

This course introduces fundamental concepts and basics of optical semiconductor devices, and their applications in optical communication systems. Topics include light emitting diodes (LEDs), Fabry-Perot and distributed feedback (DFB) laser diodes (LDs), p-i-n and avalanche photodiodes. Other optical devices such as modulators, amplifiers, filters and couplers may also be briefly covered.
