Abstract

A photonics-based approach to multi-frequency phase-coded microwave signal generation is proposed with an increased number of frequencies. Two microwave reference signals are sent to one arm of a dual-drive Mach-Zehnder modulator (DD-MZM), whereas the binary coding signal is sent to the other arm of the DD-MZM. The optical output of the DD-MZM is detected in a photodetector. Due to the nonlinearity in the electro-optic modulation, the generated photocurrent contains the nonlinear intermodulation products of the two reference signals, which are all modulated by the coding signal. An experiment is performed. Multi-frequency phase-coded microwave signals from 1 to 24 GHz with more than twelve different frequency components are generated. The performance of the generated signal including phase recovery accuracy and pulse compression capability is also verified.
