10 Gbit/s 1.55μ 25km transmission at 90°c with new self thermally compensated AlGaInAs directly modulated laser
25 March 2007
Large positive detuning is used for self thermal compensation of threshold and power variation in AlGalnAs DFB. 25 km uncompensated and non-amplified SMF transmissions are demonstrated at a constant bias current from 20°C to 90°C.
