Substrate-emitting semiconductor laser with a trapezoidal active region

Semiconductor lasers with a narrow directional pattern in the planes both parallel and perpendicular to the p - n junction are fabricated. To achieve a low radiation divergence in the p - n junction plane, the active region in this plane was designed in the form of a trapezium. The narrow directiona...

description Semiconductor lasers with a narrow directional pattern in the planes both parallel and perpendicular to the p - n junction are fabricated. To achieve a low radiation divergence in the p - n junction plane, the active region in this plane was designed in the form of a trapezium. The narrow directional pattern in the plane perpendicular to the p - n junction was ensured by the use of a leaky mode, through which more than 90 % of laser power was coupled out.
