Title	Lightwave Systems
Units	3
Prerequisites	120 and 121 or equivalent; 136 recommended.
Description	Transmission properties of optical fibers - dispersion, attenuation, nonlinear effects (solitons). Direct-detection systems: analog and digital modulation, transmitter design, receiver design, noise properties of single and multimode fiber links, dependence on source coherence, subcarrier and multichannel CATV analog transmission issues the role of optical fiber amplifiers. Coherent communication: FM noise and modulation properties of laser diodes, quantum limited detection, homodyne and heterodyne detection of various formats, laser linewidth requirements, diversity issues. Lightwave networks - WDMA, FDMA, subcarrier, TDMA, and CDMA, relative merits. Topological issues - multihop (sore-and-forward) and hot-potato routing, the role of optical switching. Optical network access protocols. Optical interconnection in high speed circuit modules and computers.
