Semiconductor Laser Quasi-Array with Phase-Locked Single-Mode Emitting Channels

The construction of a semiconductor laser with a stripe waveguide is proposed, the geometry of which can make it possible to obtain radiation similar to that of a phase-locked laser array. The requirements for the parameters of the laser quasi-array and the technological feasibility of the proposed approach are discussed.

Specific Features of the Current–Voltage Characteristic of Microdisk Lasers Based on InGaAs/GaAs Quantum Well-Dots

Injection microlasers with an active region based on arrays of InGaAs/GaAs quantum well-dots, formed by deep etching, have been studied. The manner in which the current–voltage characteristic changes when the diameter microlaser is reduced shows that a nonelectrically conducting layer with thickness of about 1.5 μm is formed near the side surface, which leads to a decrease in the effective current flow area.
