D4 - Semiconductor Optical Amplifiers (SOAs) for Optical Networking

Semiconductor optical amplifier (SOA) is a key device for future all-optical network. Not only it can serve for signal amplification, but also it is advantageous to be used for high-speed optical networking applications such as wavelength conversion, optical time division demultiplexing, and bit-level optical packet processing, etc.
This project aims to develop new techniques to alleviate patterning induced degradation in all-optical applications using SOA as well as to explore new applications of SOA for all-optical packet header/label processing.

Applications

  • All-optical demultiplexing for ultra-high speed optical time division multiplexed (OTDM) system
  • All-optical packet header/label processing

Features

  • Patterning-free demultiplexing of 40Gb/s OTDM signal to 10Gb/s
  • Robust bit-serial optical packet label swapping technique based on RZ-DPSK encoded labels
