我们报道了利用孤子自频移和多级光谱压缩实现10-GS/s 5比特实时光量子化的实验。我们证明了在10 GS/s的采样率透明的特点，通过传输10 Gb/s的多强度水平的准模拟信号，通过我们的5位光量化器。此外，为了确认我们的量化器的性能，我们测量的比特错误率和计算的有效比特数，积分非线性误差，微分非线性误差。
We report the experimental demonstration of a 10-GS/s 5-bit real-time optical quantization using the soliton self-frequency shift (SSFS) and multistage spectral compression. We prove the feature of sampling rate transparency at 10 GS/s by transmitting 10-Gb/s multi-intensity level quasi analog signals through our 5-bit optical quantizer. Furthermore, to confirm the performance of our quantizer, we measure the bit-error-rate and calculate the effective number of bits, the integral nonlinearity error, and the differential nonlinearity error.
