All-Optical Phase Quantization with High Accuracy Based on a Multiwave Interference Phase Sensitive Amplifier

All-Optical Phase Quantization with High Accuracy Based on a Multiwave Interference Phase Sensitive Amplifier

A scheme of all-optical multilevel phase quantization with high accuracy based on multiwave interference is proposed. The influences of the amplitude ratios of the conjugate (N - 1)th and (N + 1)th harmonics to the signal on phase quantization accuracy are researched. The characteristics of the phas...
