Effect of velocity fluctuations in the surface acoustic wave on functional characteristics of waveguide acoustooptic devices for real-time data processing

摘要

The characteristics of the basic acoustooptic devices (time-integrating correlator and broadband spectrum analyzer of radio signals) in which the acoustooptic chip is fabricated at a Y-cut lithium niobate substrate are studied in the presence of a relatively small velocity fluctuation of the surface acoustic wave. The main parameters of the device are scaled in accordance with its relative variations.
