An Integrated Optical RF Spectrum Analyzer

A concept for performing RF spectrum analysis using the tech-nology of Integrated Optics is described. Such devices could achieve frequency resolution of about 1 MHz over bandwidths up to 1 GHz in a very small and potentially low cost package. The principles of operation, design constraints, and possible circuit configurations are discussed. The state-of-the-art of key component technologies is also reviewed. The performance levels of the key components are nearing the point which would permit their integration in a complete circuit for a feasibility demonstration.
