Guided Wave Optical RF Spectrum Analyzer

The design, fabrication and performance of an integrated optical R.F. spectrum analyzer is described. The device consists of an injection laser, the IO substrate and a photodiode array. It operates over a frequency band-width of 400 MHz centered at 600 MHz and with a complete frame time of 2 mu sec. An R. F. input signal dynamic range in excess of 20 dB has been measured.
