Abstract

A novel scheme of header extraction for optical packet switched networks is proposed for the first time. The system is based on a modified terahertz optical asymmetric demultiplexer (TOAD) with a differential modulation scheme. Numerical analysis and simulation show that more than 15-dB contrast ratio of the separated header at 2.5 Gbit/s to the suppressed payload at 40 Gbit/s can be achieved. In addition, the semiconductor optical amplifier (SOA) TOAD parameters are discussed and designed to optimize the performance of the proposed scheme.
