The study of all-optical quantization scheme based on slicing supercuntiuum spectrum

All-optical analog-to-digital conversion play an important role in optical communication, it can re-alize the high sampling-rate, high bit-resolution by using photonic-electronic technology. All-opical quantiza-tion is a key module in all-optical analog-to-digital conversion which determine speed and resolution of the conversion directly. In this paper, we purpose a new scheme of all-optical quantization based on slicing super-contiuum spectrum and design a testifying optical circuit for simulating. The results show that the scheme is efficient for all-optical quantization.
