Photodetectors for acousto-optic signal processors

A description of devices, architecture, and performance criteria is presented for solid-state CCD and photodiode sensors useful in acousto-optic processing systems. Special attention is given to sensors used in both bulk and integrated optical acousto-optic instantaneous Fourier transform systems. The device physics of silicon photodetectors is presented in detail including discussion and analysis of quantum efficiency, responsivity, ctosstalk, charge handling capacity, data rate, optical to electrical transfer function, noise sources, dynamic range, and sensitivity. A description of new technologies, such as VHSIC and GaAs IC's which are applicable to sensor technology for AO signal processing systems is also presented.
