摘要： The present invention relates to a technique for fabricating a mechanical or visual alignment fiducial on a laser die particularly adapted for application with a laser die that is a buried structure edge emitting laser. In fabricating the device, the fiducial and the active mesa are formed in the same photolithography patterning step, using conventional techniques. The active is then buried with regrowth layers. The regrowth layers are subsequently selectively etched to expose the fiducial, leaving the active region protected and buried.

摘要： A semiconductor laser unit includes a plurality of semiconductor laser elements arranged parallel with one another in a laser beam-emitting direction, and a base for positioning and fixing the plurality of semiconductor laser elements. The plurality of semiconductor laser elements are arranged such that a laser beam emitted from the semiconductor laser element greatest in astigmatism, of the plurality of semiconductor laser elements, is coincident in its axis with a reference axis of the base. In the case that the semiconductor laser unit is arranged on an optical head device, the focusing characteristic on the plurality of laser beams can be improved.

摘要： When a laser diode assembly is manufactured, bulb-shaped solder residue is not formed on a laser diode device, a submount, or a heatsink. A laser diode assembly (30) comprises a laser diode device (12). A submount (16) is jointed on a substrate side of the laser diode device (12) with a first solder layer (14) in between. A heatsink (20) is jointed on a rear face side of the submount (16) with a second solder layer (18) in between. The submount (16) is provided with a submount groove (32) formed along border of a joint area jointed with the laser diode device (12) and an extension groove (36) extending to edges of the submount (16). Several submount thin grooves (38) whose width is smaller and depth is shallower than of the submount groove (32) are formed in the joint area of the submount in the shape of lattice and in the direction diagonally to the submount groove (32) so that the submount thin grooves (38) are spaced from each other and at least one ends of the submount thin grooves (38) contact with the submount groove (32). When solder joint of the laser diode device (12) is performed, excessive solder flows into the submount groove (32) through the submount thin grooves (38). The submount groove (32) functions as a solder pool for the excessive solder, and the excessive solder is drained outside through the extension groove (36).

摘要： A semiconductor laser has emitters that are separated by LD stripes. Grooves are formed in a mounting substrate corresponding to both ends of the semiconductor laser. On mounting, fillets are formed in the grooves by the molten solder, thereby reinforcing the soldering at both ends of the semiconductor laser and enabling uniform bonding strength to be achieved.

摘要： A laser diode bar, solder preform and heat sink are assembled prior to reflowing the solder in a manner to prevent molten solder from being drawn by capillary action over the light emitting end of the diode bar. A recessed pin 30 locates the ends of the laser bar and solder preform with respect to an edge of the heat sink so that the laser bar and solder preform overhang the heat sink edge by respective amounts. When molten, the solder will not be drawn by capillary action to obscure the light emitting end of the laser diode bar.

摘要： The present invention relates to vertical-cavity surface-emitting lasers (VCSELs), and more particularly to a method and apparatus for controlling and stabilization of polarization in such devices. The method for stabilizing the polarization of light generated by a VCSEL assembly comprising a light generation region of a VCSEL, the VCSEL being mechanically coupled to a mounting substrate, comprises the steps of: mechanically coupling the mounting substrate to a second substrate which is coextensive or larger in area than the mounting substrate, and applying uniaxial strain to the light generation region of the VCSEL by means of external strain applied to the mounting substrate by the second substrate or by means attached to the second substrate.
