Abstract :
We introduce our recent works on AlGaInAs quantum-well lasers with semi-insulating buried-heterostructure for ultra-high-speed transmission. The short-cavity DFB lasers show high-speed direct modulation at 25 and 40 Gbps, and the distributed reflector lasers with shortened active-region length provide reduced driving current in ultra-high-speed direct modulation.
