  • Patent number: 10135222
    Abstract: A VCSEL package including a VCSEL, a housing, containing the VCSEL, and a diffuser operably attached to the housing and configured to receive an emitted beam of light from the VCSEL and produce a beam of predetermined angular divergence. The housing may be a PLLC package, a ceramic package, or a TO-style package. The diffuser could be a substantially planar diffuser sheet, which in some cases may be comprised of glass or plastic. In some embodiments, the diffuser could be a diffractive optical element or holographic light shaping diffuser. In some embodiments, the diffuser can be designed to produce a beam with an illumination full angle of up to about 90 degrees.

  • Publication number: 20180226768
    Abstract: VCSELs and methods having improved characteristics. In some embodiments, these include a semiconductor substrate; a vertical-cavity surface-emitting laser (VCSEL) on the substrate; a first electrical contact formed on the VCSEL; a second electrical contact formed on the substrate, wherein the VCSEL includes: a first resonating cavity having first and second mirrors, at least one of which partially transmits light incident on that mirror, wherein the first second mirrors are electrically conductive. A first layer is between the first mirror and the second mirror and has a first aperture that restricts the path of current flow. A second layer is between the first layer and the second mirror and also restricts the electrical current path. A multiple-quantum-well (MQW) structure is between the first mirror and the second mirror, wherein the first and second apertures act together to define a path geometry of the current through the MQW structure.

  • Patent number: 9991673
    Abstract: An optical package having a patterned submount, an optoelectronic device mounted to the patterned submount, a spacer affixed on one side to the patterned submount, the spacer having a bore hole therethrough wherein the optoelectronic device is positioned, and an optical element affixed to the spacer on a side opposite the patterned submount and covering the spacer bore hole. The patterned submount may be a circuit board. The optoelectronic device may be a VCSEL. The spacer may be affixed to the circuit board, for example, using an epoxy preform or an adhesive laminate. The spacer may, for example, be manufactured from a sheet of stainless steel or from a circuit board. The optical element may be, for example, a diffuser, a concave lens, a convex lens, a holographic element, polarizers, or diffraction gratings. The optical element may be affixed to the spacer using an epoxy preform or an adhesive laminate.
