[ 1 ] - Improving the Thermal Characteristics of Semiconductor Lasers Using a New Asymmetric Waveguide Structure
Self-heating leads to a temperature rise of the laser diode and limits the output power and efficiency due to increased loss and decreased differential gain. To control device self-heating, it is required to design the laser structure with a low optical loss, while the heat flux must spread out of the device efficiently. In this study, a new asymmetric waveguide design is proposed and th...
[ 2 ] - Self-Consistent Analysis of Barrier Characterization Effects on Quantum Well Laser Internal Performance
In this paper, a numerical study of barrier characterization effects on the high-temperature internal performance of an InGaAsP multi-quantum well laser is presented. The softwareused for this purpose self-consistently combines the three-dimensional simulation of carrier transports, self-heating, and optical waveguiding. The laser model calculates all relevant physical mechanisms, including the...
