Resolution-enhanced ultrafast ADC using optical multi-period transfer functions of NOLMs
Ultrafast processes in fibers Fiber optics sensors
2015/6/9
We propose a resolution enhancement scheme using optical input/output multi-period transfer functions of NOLMs for ultrafast low-resolution ADCs. This scheme can provide a resolution of 8.8 ENOB by co...
Optical Comb and Filter Bank (De)Mux Enabling 1 Tb/s Orthogonal Sub-band Multiplexed CO-OFDM Free of ADC/DAC Limits
Optical Comb Filter Bank (De)Mux Enabling Multiplexed CO-OFDM ADC/DAC Limits
2015/7/17
Realizations of 100-1000Gb/s CO-OFDM are hindered by electronic ADC/DAC rates. By(de)multiplexing the OFDM sub-bands by means of optical-comb generators with repetition rate matched to sub-band separa...
