Paper Abstract

A novel optical spectrum compression scheme based on time-dependent filtering is proposed and demonstrated. The spectrum compression is realized by using nonlinear polarization rotation effect to achieve power-dependent filtering of a chirped soliton pulse. In the experiment, a single-stage spectrum compression unit based on the proposed scheme is employed in the soliton self-frequency shift-based optical quantization system to improve the quantization resolution. The experimental results show that an average output spectrum width of 1.5 nm is obtained using the proposed scheme, which is 68% of that using the traditional comb-like fiber scheme. In addition, the quantization resolution using the proposed scheme is 5.1 bits, which is 0.6 bit higher than that using a single-stage spectrum compression unit based on the traditional comb-like fiber structure.
