Abstract

A technique to determine experimentally the amplitude - phase coupling factor (α factor) in semiconductor laser diodes is proposed. The factor was obtained for InGaAs/AlGaAs/GaAs single-quantum-well lasers with injected-carrier concentrations from 1.5 × 10¹⁸ to 6 × 10¹⁸ cm^-3. It is shown that the α factor for such structures at the maximum of mode gain lies in the range 2-9, and its value for one and the same structure may differ severalfold, depending on the operating point of a laser.
