Abstract :
By exploiting electronic and thermal tuning by forward and backward biasing the tuning region, a record continuous tuning range of 11nm has been achieved with an improved strained-layer (SL) multiquantum-well (MQW) TTG DFB laser at 1.55 mu m wavelength. Over a wavelength range of 9.2nm an optical power above 1mW and a spectral linewidth below 30MHz can be maintained with 400 mu m long devices.
