摘要：

In this paper, we optimize a proposed all-optical quantization scheme based on soliton self-frequency shift (SSFS) and pre-chirp spectral compression techniques. A 10m-long high-nonlinear photonic crystal fiber (PCF) is used as an SSFS medium relevant to the power of the sampled optical pulses. Furthermore, a 10m-long dispersion flattened hybrid cladding hexagonal-octagonal PCF (6/8-PCF) is utilized as a spectral compression medium to further enhance the resolution. Simulation results show that 6-bit quantization resolution is still obtained when a 100m-long dispersion-increasing fiber (DIF) is replaced by a 6/8-PCF in spectral compression module.
