Abstract :
Phase-encoded optical sampling allows the processing of RF and microwave signals with high linearity and >60-dB signal-to-noise ratio in an optically sampled digital receiver. The wide analog-input bandwidth (>1 GHz) enables novel processing capabilities as demonstrated for a 250-MHz-bandwidth chirped signal undersampled at 60 MS/s.
