Abstract — A new hybrid opto-electronic WDM architecture to extend electronic ADC performance is analyzed and simulated. Mode-locked optical pulses are amplitude modulated by a RF signal and optically demultiplexed into a number of parallel channels. The signal in each channel is converted to an electrical signal and then passed through a simple low-pass filter. The effect of low-pass filter re...
