1.54 μm InAs/InP p-type doped quantum-dash-based DFB lasers for isolator-free operation
Résumé
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
