Abstract

There is considerable interest in the application of the guided optical wave Bragg interaction with surface acoustic waves (SAW) to rf spectrum analysis.^1-3 The major part of this effort has been directed toward producing demonstration models of integrated devices with typical bandwidth and resolution capabilities of ~400 and 4 MHz, respectively. Our objective has been to investigate the acoustooptic interaction in Ti-diffused lithium niobate (LiNbO₃) waveguides at frequencies in excess of 1 GHz. A particular goal is to develop a guided-wave analyzer with a 1-GHz octave bandwidth and 1-MHz resolution. In this paper we report on our progress to date.
