    摘要: A vertical cavity surface emitting laser (VCSEL) structure includes a bottom distributed Bragg reflector (DBR) arranged over a substrate; a metal layer interposed between the bottom DBR and the substrate, wherein the metal layer and bottom DBR form a composite mirror structure. A patterned dielectric layer may be interposed between the metal layer and the bottom DBR to reduce a deleterious chemical reaction between the metal layer and the bottom DBR. The metal layer directly contacts a portion of the bottom DBR to enhance the electrical and thermal conductivity of the VCSEL structure.

    摘要: A vertical cavity surface emitting laser having an oxidizable layer oxidized with enhanced lateral oxidation. The oxidation may involve adding oxygen in the form of a fluid, with or without other fluid such as water vapor, in the oxidizing environment, and/or in the layer to be oxidized. This oxidation approach may be used for layers with relatively low aluminum content such as in InP based structures, or with high aluminum content such as in GaAs based structures.

    摘要: A long wavelength vertical cavity surface emitting laser having a substrate, a first mirror situated on the substrate, an active region situated on the first mirror, a second mirror situated on the active region. The first mirror may have several pairs of layers with an oxidized layer in one or more pairs of that mirror. The substrate may include InP and the mirror components may be compatible with the InP. The one or more layers in the first mirror may be oxidized via a trench-like approach or other arrangement.

    摘要: A VCSEL includes a substrate having a partially removed portion; a metal-assisted DBR having a metal layer and a first mirror stack, wherein the metal layer is located at the partially removed portion of the substrate; an active region having a plurality of quantum wells over the metal-assisted DBR; and a second mirror stack over the active region, wherein a number of alternating layers of the first mirror stack is substantially smaller than a number typically required for a VCSEL without the integrated metal reflector. Such a metal-assisted DBR is especially useful for a long-wavelength VCSEL on a InP substrate or a red-color VCSEL on a GaAs substrate.

    摘要: The invention is generally concerned with vertical cavity surface emitting lasers. In one example, the vertical cavity surface emitting laser includes, among other things, an upper mirror structure having a metal contact, a top mirror above the metal contact, and a semiconductive top DBR having an insulation region, wherein the top DBR is no more than 3.5 microns thick and is disposed below the metal contact. Thus, the top DBR is sufficiently thick as to enable adequate current spreading, but thin enough to enable fabrication of an isolation region using relatively low energy ion implantation or relatively shallow etching.
