摘要： An array of laser diode emitters is used as an illumination source for a range imaging system. The laser diode emitters are disposed on a common substrate. When one of the emitters fails, the remaining emitters emit enough light to meet the output optical power specification. The emitters can be disposed with a tight spacing. The tight spacing facilitates packaging of the entire array into a compact single package on a common heat sink.

摘要： The invention concerns an optical waveguide transition and its fabrication method, enabling coupling between a buried optical waveguide and a ridged optical waveguide. The transition structure is formed during etching of a layer containing the buried optical waveguide, the transition area being formed by adiabatically increasing the lateral dimensions of the buried waveguide. Top layers are deposited on the buried waveguide and its widened structure in the transition area, and the ridged optical waveguide is fabricated with one part on top of the transition area. Coupling of the respective propagation modes in the buried and ridged waveguides is effected by mode adaptation in the region between the two waveguide structures in the transition area. The transition of the invention is made in two conventional epitaxy steps.

摘要： Embodiments of the present disclosure are directed towards a laser device with a stepped graded index separate confinement heterostructure (SCH), in accordance with some embodiments. One embodiment includes a substrate area, and an active region adjacent to the substrate area. The active region includes an SCH layer, which comprises a first portion and a second portion adjacent to the first portion. A composition of the first portion is graded to provide a first conduction band energy increase over a distance from multiple quantum wells (MQW) to a p-side of a laser device junction. A composition of the second portion is graded to provide a second conduction band energy increase over the MQW to the p-side distance. The first conduction band energy increase is different than the second conduction band energy increase. Other embodiments may be described and/or claimed.

摘要： In a laser device, notably for optical pumping, the wafer includes an expansion segment adjacent the exit to prevent degradation of the exit facet of the semiconductor wafer that constitutes the amplifying part of the laser. The other facet is reflective and a Bragg grating is formed in a coupling fiber disposed near the exit facet. Applications include optical pumping of erbium-doped fiber amplifiers.
