摘要: The present invention provides a Vertical Cavity Surface Emitting Laser including: a first multilayer film reflector; an active layer having a light emission region; a second multilayer film reflector; and a reflectance adjustment layer in this order on a substrate side. The first multilayer film reflector and the second multilayer film reflector have a laminated structure in which reflectance of oscillation wavelength λx is almost constant without depending on temperature change. The active layer is made of a material with which a maximum gain is obtained at temperature higher than ambient temperature. The reflectance adjustment layer has a laminated structure in which difference ΔR(=Rx−Ry) between reflectance Rx of a region opposed to a central region of the light emission region and reflectance Ry of a region opposed to an outer edge region of the light emission region is increased associated with temperature increase from ambient temperature to high temperature.

摘要: In a VCSEL, a first multilayer film reflector, an active layer having a light emitting central region, a second multilayer film reflector, and a transverse mode adjustment layer are layered in this order. The first multilayer film reflector has a quadrangle current injection region with an intersection of diagonal lines corresponding to the light emitting central region. The second multilayer film reflector has a light emitting window provided in a region corresponding to one diagonal line of the current injection region and a pair of grooves provided with the light emitting window in between. The transverse mode adjustment layer is provided correspondingly to the light emitting window, and reflectance of a peripheral region thereof is lower than that of a central region thereof.

摘要: A method of manufacturing a laser diode array capable of inhibiting electric cross talk is provided. The method of manufacturing a laser diode array includes a processing step of forming a peel layer containing an oxidizable material and a vertical resonator structure over a first substrate sequentially from the first substrate side by crystal growth, and then selectively etching the peel layer and the vertical resonator structure to the first substrate, thereby processing into a columnar shape, a peeling step of oxidizing the peel layer from a side face, and then peeling the vertical resonator structure of columnar shape from the first substrate, and a rearrangement step of jointing a plurality of vertical resonator structures of columnar shape obtained by the peeling step to a surface of a metal layer of a second substrate formed with the metal layer on the surface.

摘要: A surface emitting semiconductor laser device which can be manufactured easily and inexpensively and in which the direction of polarization of a laser beam can be controlled into a fixed direction. An oxidizing treatment is applied to a current confinement layer to form a current passage region in a rectangular shape having an in-plane anisotropy. In addition, a pair of trenches with their side surfaces, on the side of a beam outgoing aperture, set to be parallel to either of the diagonal direction of the current passage region is provided at opposite positions with the beam outgoing aperture as a center therebetween. The direction of polarization of the laser beam made to go out through the beam outgoing aperture is specified into only one direction, whereby the direction of polarization can be accurately controlled to a fixed direction. Besides, where the trench or trenches are filled with a metallic material or insulating material which is absorptive with respect to the laser beam, the polarization ratio of the laser beam is further enhanced.
