Multichannel acousto-optic bragg cells: crosstalk minimization utilizing self- collimating acoustic modes

摘要

Acousto-optic Bragg cell devices provide the most effective way of imparting electrical information in transducer substrate, extend the power of optical processing in a compact package to simulatneous multichan- nel signal analysis applications. Multichannel Bragg cell design principles utilizing acoustically anisotropic acousto-optic materials and RF stripline techniques to achieve high multichannel Bargg cell performance will be described. Multichannel Bragg cell parformance using these design principles will be presented. An optical processing system using a multichannel Bragg cell for multichannel RF spectrum analysis will also be discussed.
