Abstract
In this dissertation for the first time optical and RF analysis of MQW modulator has been reported for analog fiber optic link considering overall RF bandwidth, linearity and carrier to noise criteria. Experimental data from AT&T Bell Labs, and other research laboratories has been acquired. The principle of quantum well modulator has been discussed. First time the design optimization procedure is outlined for linearly modulated multiple quantum well waveguide electro-absorption modulator. Broadband video transmission system is designed for 60 channels, 450 MHz NTSC frequency plan with Optical Modulation Index per video carrier of 3.25% and modulator optical insertion loss of less than 5 dB.
