Paper Abstract

This paper describes the integrated optic implementation of a Bragg spectrum analyzer which utilizes a surface-guided coherent optical wave and a surface acoustic wave. The Integrated Optic Spectrum Analyzer (IOSA) employs surface geodesic lenses for beam focusing, a surface acoustic wave input transducer, an optical surface waveguide, a solid state laser and a detector array coupled to the waveguide. Design principles are given to selecting component parameters such as optical beam diameter, detector cell size, lens apertures and focal lengths, acoustic transducer design and input power level so as to obtain specific RF resolution, spurious level and signal to noise ratio. Design parameters are.presented for a 400 to 800 MHz spectrum analyzer with a projected resolution of 4 MHz, and a 40 dB dynamic range.
