    摘要: To provide a semiconductor laser that suppresses end face destruction due to catastrophic optical damage (COD) to a light emission end face and has high output characteristics.An n-type clad layer, a current block layer, an active layer, and a p-type clad layer are provided over an n-type substrate whose major plane has an off-angle in a direction from a (0001) plane. For example, the current block layer is arranged on both sides of a current constriction area. Then, the current block layer is arranged so as to be retracted from a cleavage plane (line). In this case, in the active layer having a quantum well structure that is crystal-grown over the n-type clad layer and the current block layer, the layer thickness of a window area from the cleavage plane (line) up to the end part of the current block layer is smaller than the layer thickness of the current constriction area (area between the current block layers). As a result, the band gap of the active layer in the window area becomes large, and thus it is possible to suppress end face destruction due to the COD.

    摘要: A cathode electrode, cathode pad electrodes, cathode wiring electrodes, an anode electrode, an anode pad electrode, and an anode wiring electrode are disposed on the surface of a vertical-cavity surface-emitting laser device. A light-emitting-region multilayer portion having active layers sandwiched by clad layers and DBR layers is formed directly below the anode electrode. A region where the light-emitting-region multilayer portion is formed serves as a light-emitting region. The light-emitting region is positioned closer to one end of the first direction than is a suction region onto which a flat collet sucks with respect to the first direction, in such a way that the light-emitting region is substantially in contact with or spaced a predetermined distance from the suction region.

    摘要: A laser diode includes a substrate and a junction layer disposed on the substrate. The junction layer forms a quantum well of the laser diode. The laser diode includes a junction surface having at least one channel that extends through the junction layer to the substrate. The at least one channel defines an anode region and a cathode region. A cathode electrical junction is disposed on the junction surface at the cathode region, and an anode electrical junction is disposed on the junction surface and coupled to the junction layer at the anode region. A cathode metal layer is disposed in at least a trench region of the channel. The cathode metal layer couples the substrate to the cathode electrical junction.

    摘要: This description relates to an apparatus, a method of manufacturing, and a method of tuning optical and/or electrical parameters of semiconductor devices and materials, thin film materials, or other devices. In one example, a laser is tuned to produce an adjustable output wavelength by coupling the laser to a tuning material or base such as, for example, a piezoelectric base using a suitable attachment method. The laser includes of a tunable material that is sensitive to stress and/or strain. Stress and/or strain applied to the laser from the tuning material results in an electronically variable output wavelength. As an example, applying a voltage to a piezoelectric base that serves as a tuning material can cause the base to expand or contract, and the expansions and contractions from the base are coupled to the tunable material of the laser, thus varying the wavelength of the output light from the laser. Additionally, other devices that are sensitive to stress and/or strain can be adjoined in a similar manner and can result in an electronically variable output of the devices. Examples of other embodiments are also disclosed herein.
