Dynamically Reconfigurable All Optical Frequency Measurement System

Abstract

A microwave photonic frequency measurement system is demonstrated practically. The system employs the four-wave mixing effect in a highly nonlinear fiber to produce a low-frequency output voltage, which is a function of input RF frequency. Using an algorithm that allows dynamic reconfiguration, the system is able to instantaneously monitor a broad frequency range for threat signals and to provide fast yet accurate frequency measurement. An operating frequency range of 0.04–40 GHz with at most 0.016% error is achieved.
