EAM modulated DBR laser array for TWDM-PON applications
2016
4 Channel DBR laser arrays are fabricated for use in optical line terminals of TWDM-PON systems. These combine 1.4Q InGaAsP material in the DBR with EAMs using the identical active layer design. A tuning range ∼10 nm and extinction ratio of >27 dB are measured.
