Abstract

Edge-emitting diode lasers with shallow location of a quantum-well active region at a depth of 0.92 μm were developed and their thermal resistance was evaluated from the analysis of true spontaneous emission spectra through the top contact window. Owing to a close spacing between the active region and laser heatsink, effective heat removal is achieved under continuous wave operation that is characterized by a low value of specific thermal resistance of 6 × 10^–3 K/(W cm²).
