提出了一种用于超快异步突发光分组标签识别的全光串并转换（SPC）新方案。采用光纤阵列或面发射平面光波电路开发了紧凑的SP转换模块，并利用该模块演示了16位光分组的1-Tbit/s和40-Gbit/s SPC。转换器的关键器件是一个自旋极化表面反射全光开关（LOTOS），具有超快的开关时间（250 fs）和极高的开/关比（>30 dB）。利用光时钟脉冲发生器、互补金属氧化物半导体（CMOS）电子电路以及全光SP转换器，实验验证了40 gbit /s 16位突发模光包的标签识别。根据路由表，还演示了使用从CMOS电路产生的2通道控制信号的1 x 4自路由。
A novel scheme for all-optical serial-to-parallel conversion (SPC) is proposed for label recognition of ultrafast asynchronous burst optical packets. Compact SP converter modules were developed using a fiber array or a surfaceemitting planar lightwave circuit, and 1-Tbit/s and 40-Gbit/s SPC for 16-bit optical packets is demonstrated using the modules. The key device in the converter is a spin-polarized surface-reflection all-optical switch (LOTOS) with an ultrafast switching time (250 fs) and an extremely high on/off ratio (>30 dB). Label recognition of 40-Gbit/s 16-bit burst-mode optical packets is experimentally confirmed using an optical clock-pulse generator and a complementary metal-oxide-semiconductor (CMOS) electronics circuit as well as the all-optical SP converter. 1 x 4 self-routing is also demonstrated using 2-channel control signals generated from the CMOS circuit according to a routing table.
