Abstract :
The temperature dependence of the characteristics of high performance lasers for lightwave communications is an important consideration. The p-dopant profile has a direct impact on manufacturing yield, wavelength chirp, and laser modulation speed. The p-dopant is now also believed among the material parameters affecting temperature performance. In this work, the performance of GaInAsP-InP 1.3 μm multi-quantum well (MQW) lasers was investigated in relation to the p-dopant profile in the MQW, separate confinement (SCH) and InP p-cladding layers. All solid sources were used in the fabrication of the devices, which were grown by molecular beam epitaxy
