40-Gbps Transmission Using Direct Modulation of 1.3-μm AlGaInAs MQW Distributed-Reflector Lasers up to 70oC
Semiconductor lasers
2015/5/25
40-Gbps transmission over 5-km single-mode fiber using a directly modulated 1.3-μm AlGaInAs MQW distributed-reflector laser was demonstrated. Error-free operations up to 70oC have been achieved.
I will overview our recent results on ultra-long lasers and will discuss the concept of a fiber laser with an open cavity that operates using random distributed feedback provided by Rayleigh scatterin...
