Metal-assisted DBRs for thermal management in VCSELS |
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.
