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
