提出并实现了基于Fabry-Pe/spl锐/腐半导体激光器（FP-LD）中横磁（TM）模吸收和自相位调制（SPM）的10 Gb/s非归零（NRZ）到伪归零（PRZ）数据格式转换。FP-LD对TM模注入光束具有吸收零点，具有NRZ数据的光束经历SPM，这在每个上升沿和下降沿处引起频率啁啾。通过提取啁啾分量，实现了NRZ到PRZ的全光格式转换。所得到的PRZ数据给出了定义良好的10 Gb/s时钟信号。该方法对于高速光通信系统的全光时钟恢复非常有用。
We propose and demonstrate nonreturn-to-zero (NRZ) to pseudoreturn-to-zero (PRZ) data format conversion at 10 Gb/s based on transverse-magnetic (TM) mode absorption and self-phase modulation (SPM) in a Fabry-Pe/spl acute/rot laser diode (FP-LD). An FP-LD has absorption nulls for TM mode injected beam and the beam having NRZ data experiences SPM, which induces a frequency chirp at every rising edge and falling edge. By extracting the chirp components, all-optical NRZ-to-PRZ format conversion has been achieved. The resultant PRZ data gives well-defined 10-Gb/s clock signal. This method will be very useful in all-optical clock recovery of high-speed optical communication systems.
