摘　　要：提出一种基于多个并行Sagnac环梳状滤波器实现波长编码的方法,可用于孤子自频移全光模数转换的光学编码.仿真结果表明:该方法在1 601nm^1 707nm孤子自频移波段成功实现了5bits的光学编码,最大微分线性误差和积分线性误差分别为0.088LSB和0.482LSB.与其他波长编码方式相比,该方法结构简单、工作波长范围宽,并且具有非常好的编码位数扩展性.A novel optical coding scheme employing parallel Sagnac-loops is proposed for all-optical analog-to-digital converters based on soliton self-frequency shift eHect. The proposed coding scheme is numerically demonstrated in a 5-hit SSFS-hased all-optical ADC with a wavelength range of 1 601 nm to 1 707 nm, where the results show that the maximum differential nonlinearity error and the integral nonlinearity error are 0.088 and 0.482 Least Significant Bit （LSB）, respectively. Compared with other wavelength coding counterparts, the proposed optical coding scheme has a simple architecture and a broad operation wavelength range, and is easy to achieve a larger coding hit.
