Multiband Linearly Frequency-Modulated Signal Generation Based on an Optical Integrated Cascade Microring Filter
A novel microwave photonic multiband linearly frequency-modulated (LFM) signal generation scheme based on an optical integrated cascade microring filter for microwave photonic radar is proposed and demonstrated. Due to the tunable filtering ability of the cascade microring resonator, the proposed signal generation scheme can filter out the LFM signals, multicast by an optical frequency comb (OFC). An 8-channel LFM signal generator covering S, C, Ku bands with a bandwidth of 1 GHz is achieved in experiment and the 8 channels can switch between each other.
