    摘要: A VCSEL (113) having a first and a second stack of distributed Bragg reflectors (120, 116) and an active region (118) is formed. Conductive layers (108 and 109) having an opening is formed on the second stack of distributed Bragg reflectors (116). A first region (104), a second region (106), and a third region (108) are formed in the opening of the conductive layer (108), thereby providing a contact to both the second stack of distributed Bragg reflectors (116) and to the first region (104). An insulative layer (220) is disposed on the substrate (124), thereby insulating the second region (106) from the conductive layer (108). A conductive layer (134) having second opening disposed substantially overlying the first opening, thereby electrically coupling the third region (108) to the conductive layer (134) with the second opening allowing a light (121) to pass.

    摘要: A semiconductor laser package and method of fabrication including a vertical cavity surface emitting laser and a power monitoring system, such as a photodetector mounted on a mounting base. An optical element, such as a beam splitter, formed integral with the mounting base or as a separate element positioned on the mounting base in optical alignment with an emission generated by the vertical cavity surface emitting laser. The optical element characterized by reflecting a portion of the emission in the direction of the photodetector and allowing a portion of the emission to pass therethrough. An overmolded housing is positioned on the mounting base to enclose the vertical cavity surface emitting laser, the photodetector and the optical element.

    摘要: Patterned-mirrors for VCSELs are fabricated by forming a first mirror stack of a plurality of pairs of relatively high and low index of refraction layers, forming an active region of aluminum-free material on the first mirror stack, and forming a second mirror stack of a plurality of pairs of relatively high and low index of refraction layers. The second mirror stack includes first and second portions of materials selected to provide different rates of etching between the first and second portions. The second portion is selectively etched to the first portion by utilizing the first portion as an etch stop.
