Code synchronization in all-optical analog-to-digital conversion based on lumped time-delay compensation scheme

In this paper, we propose a lumped time-delay compensation scheme for the all-optical analog-to-digital conversion (ADC) based on solit on self-frequency shift (SSFS) and optical interconnection techniques. By inserting a length of photonic crystal fiber (PCF) between quantization and coding modules, the time-delay of quantized pulses can be compensated.
