    摘要: A method of fabricating VCSELs including the steps of epitaxially growing a first mirror stack of a first conductivity type, an active region on the first mirror stack, and a first portion of a second mirror stack of a second conductivity type on the active region. A dielectric layer is then formed on the first portion of the second mirror stack, patterned to define an operating region and a remaining portion of the second mirror stack is epitaxially grown on the first portion to form a complete second mirror stack. Portions of the second mirror stack overlying the dielectric layer are polycrystalline in formation and substantially limit the remaining portion of the second mirror stack to the operating region. The polycrystalline layers can then be removed and electrical contacts formed.

A first cladding region is disposed on the first stack of distributed Bragg mirrors. An active region is disposed on the first cladding region with a second cladding region being dispose on the active region. A second stack of distributed Bragg mirrors having alternating layers of aluminum gallium arsenide differing concentrations of aluminum are disposed on the second cladding region with a second plurality of continuous gradient layers being positioned between the alternating layers of differing aluminum concentrations to dynamically change the aluminum concentration from one of the altering layers to another alternating layers.

    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.
