Abstract	:	For long-haul ber-optic communication systems, the development of ecienthigh-speed photodiodes and transistors compatible with each other is essentialfor monolithic integration. This dissertation details the design, fabrication, andcharacterization of InP-based photodiodes and HEMTs suitable for operating inthe low-loss low-dispersion window of the optical bers used in telecommunicationsystems. High-speed photodiodes with bandwidths as high 60 GHz and a responsivityof 0.3 A/W have been achieved using a dual-depletion design. To achievebetter bandwidth-eciency products, a novel drift-enhanced dual-absorption designwas developed and demonstrated. Diodes fabricated with this design achievedbandwidths of 30 GHz with a responsivity of 0.82 A/W. Numerical and analyticalanalyses have been performed to understand the bandwidth limitations ofthese photodiodes to optimize their performance. Ultrafast HEMTs with cutofrequencies over 200 GHz have been demonstrated using a 0.1 m T-gatetested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
