Semiconductor Optical Amplifier for Amplification and Switching Applications

摘要

This paper presents recent progress on SOAs with dilute optical mode. The SOA optical mode is designed to be large to achieve high saturation power and low coupling losses of 1.16 and 0.89 dB for TE and TM polarizations with a lens fiber. A 2-mm long SOA has high saturation power (16.3 dBm), low PDG (<1dB), low noise figure (<7.2 dB) and medium gain (>19.5 dB) across C-band. A 1.5mm-long SOA was successfully used as a 10 Gbit/s booster amplifier for 100km transmission. The dynamic properties of the SOA were characterized to support application as optical gate switch in sub GHz speed.
