Abstract
Time-slot assignment (TSA) functions including time-slot interchange and serial-to-parallel and parallel-to-serial conversions, and optical compressor are investigated using an optical buffer with a large variable delay range based on active vertical coupler crosspoint switch. The variable delay range could be achieved from 1 to 999 time slots in the proposed scheme, and correspondingly, the length of time slot is flexible. It is demonstrated that the experiments could be performed even at a data rate of 10 Gb/s with power penalties of about 1.5 and 5.6 dB compared with back-to-back when the packets pass through two buffers and one buffer nine times.
