Paper Abstract

The integrated optic spectrum analyzer is a device which utilizes the Bragg interaction between a SAW and a guided optical beam to perform spectral analysis. Hughes has developed the first fully integrated IOSA which uses a butt-coupled GaAlAs semiconductor laser, a LiNb03 waveguide substrate, a 400 MHz bandwidth SAW transducer and a silicon detector/CCD array chip. The completed device exhibited a 3 dB bandwidth of 380 MHz with 10%/watt deflection efficiency at ), = 0.82 μm. The RF resolution was found to be 8 MHz and the dynamic range was greaterPthan 20 dB. Data is also discussed on a modified chirp transducer which exhibits a 450 MHz acousto-optic bandwidth with a center frequency of 1.0 GHz.*
