Abstract :
We present all-optical analog-to-digital conversion using optical time-interleaving and demonstrate dynamic 8-period input/output optical transfer function of PM-NOLM with dynamic counter-propagating effect compensation, usable for 5-bit quantizing and encoding, a crucial number for the front-end of DSP.
