Abstract: An optical fiber is coupled along an edge of a rectangular GaAs injection laser. A circulatory mode of light reflection is established between the four side walls of the laser at an angle of incidence which provides a narrow rectangular strip of light. The fiber is positioned transversely at one reflection point or corner of the light path. A narrow rectangular metal strip contact on one face of the laser confines current to the desired path. A reflective coating on an end of the fiber may provide a unidirectional optical source. Other variations include an optical amplifier for a light input source and an optical coupler from an input fiber to an output fiber.

Abstract: The coupling of an injection laser diode into an optical fiber is improved by a short resonating length of fiber. A partially reflective layer is positioned at the remote end of the resonator section and a highly reflective layer with an aperture slit and anti-reflection layer in the slit are disposed at the laser end. A circulatory laser mode can also be improved using a resonator section with a matching interference layer at the coupling point. A rectangular contact strip confines current to the desired circulating area. Another variation includes two different coupling points with one more tightly coupled than the other for circulating light in one direction.

Abstract: A semiconductor injection laser device is provided with a narrow junction structure between layers of GaAs and GaAlAs which confines current flow and optical energy to minimize losses. Particular doping and layer growing techniques provide a central strip or ridge in the p-n junction extending between the end faces of the two layers. In one variation the junction crosses an intermediate GaAs layer between two outer GaA1As layers.
