Abstract
We report temperature dependent optical modal gain and absorption features as function of injection current of 1.55 μm InAs Q-Dash laser with an InAs/InAlGaAs/InP structure monolithically grown on (001) silicon substrate. Board-area multi-segmented contact devices were fabricated and driven by pulsed current. Net modal gain and absorption was obtained by measuring amplified spontaneous emission using the variable stripe-length method. From 20˚C to 80˚C, the changes in maximum gain and gain bandwidth were studied and a redshift in peak gain wavelength was observed. Quantum confined Stark effect was measured under reversed bias from -1 V to -7 V.
