Abstract
Mesastripe single-mode InGaAsP/InP laser diode heterostructures with an optical emission power of 200 mW in the continuous lasing mode at two wavelengths (1.3 and 1.55 μm) were obtained by metalorganic VPE. In the samples with a mesastripe contact width of W=5 μm, the single-mode lasing regime was observed in the entire range of pumping currents. For a cavity length of 1.0–2.5 mm, the threshold current densities varied within 450–600 A/cm2. The differential quantum efficiency reached 30–40%. The internal optical losses in the mesastripe laser heterostructures are reduced to 7.7 cm−1. The output power-pumping current characteristics of control samples remained unchanged upon testing for 1500 h at 50°C.
