40-Gbit/s label recognition and 1 /spl times/ 4 self-routing using self-serial-to-parallel conversion

Label recognition of 40-Gbit/s 16-bit burst-mode optical packets is demonstrated using an optical clock-pulse generator, an all-optical serial-to-parallel converter, and a CMOS electronics circuit. A compact 16-channel all-optical serial-to-parallel converter module was developed using a surface-emitting planar lightwave circuit and a spin-polarized surface-reflection all-optical switch made of low-temperature grown Be-doped strained InGaAs/InAlAs multiple quantum wells. 1 /spl times/ 4 self-routing is also demonstrated using two-channel control signals generated from the CMOS circuit according to a routing table.
