1.54microns InAs/InP p-type doped quantum dash based DFB lasers for isolator free operation
01 January 2010
: The tolerance to optical feedback of p-type doped InAs/InP quantum dash based DFB lasers is investigated. Optimized devices show a record -18 dB onset of coherence collapse compliant with 10 Gb/s Ethernet standard for isolator-free operation. 1. Introduction
