Improving the steering efficiency of 1/spl times/4096 opto-VLSI processor using direct power measurement method

Abstract

We report optimization of the steering efficiency of the 1-D opto-VLSI processor using direct power measurement method for wavelengths in the near-IR and 632 nm. Highest improvement observed for the signal and interport isolation is 8 dB and 12 dB respectively. This improved performance of the processor is crucial to the realization of low crosstalk reconfigurable optical add/drop multiplexers (ROADM) using opto-VLSI processors.
