Optoelectronic Components and Integrated Circuits Including Up and Down Conversion Technique and Hybrid Integration Technology

Microwave optical links can be considered as basic bricks for some emerging system applications such as optically supplied microwave antennas. Emitters, optical switching matrices, high speed photodetectors and specific components for up or down conversion, are generic devices or functions for microwave optical links. We will describe main ways to generate microwave or millimetre wave signals through an optical fibre: direct and external modulation, optical control of microwave oscillators, generation of harmonics with laser non-linearities, dual mode emitters, with emphasis on new explored ways. Optical switching matrixes, which are basic photonic integrated circuits for optical processing are also examined, with recent crosstalk and phase noise results. The problem related to high speed photodetectors are also detailed with emphasis on waveguide photodetectors. The problem of up and down conversion is developed through specific optoelectronic devices. At last, we discuss the monolithic integration of optoelectronic or photonic devices, recalling that the industrial way is based on hybrid technology on silicon mother board, and we suggest new ways for the future.
