Abstract :
A report is presented on continuous-wave (CW) singlemode operation of a distributed feedback GaInAsN laser diode at 1295 nm. A sidemode supression ratio of 43 dB is obtained at 60 mA drive current. Small signal modulation bandwidth measurements show a record 3 dB cutoff frequency of 13.8 GHz.
