Abstract :
A novel complex-coupled InGaAsP/InP integrated twin guide distributed feedback (ITG-DFB) laser with a substantially simplified fabrication process made by single step epitaxy without corrugation overgrowth is described. Room temperature CW operation with a threshold current of 45 mA and a SMSR in excess of 40 dB is demonstrated
