Abstract
Laser diodes that include a mirror stack on the light-exit facet. The mirror stack has a reflectivity into the active region that is greater in air than when the laser diode is integrated into an apparatus. Related apparatuses, data storage devices, computing systems, and methods.
Claims20
A laser diode comprising:
- a body of one or more non-self-supporting layers of crystalline material, wherein the body has a light-exit facet at an end of the body, and wherein the body comprises an active region of the laser diode;
- and
- a mirror stack on the light-exit facet, wherein the mirror stack comprises two or more layers of dielectric material, wherein the mirror stack has a reflectivity into the active region that is greater in laser diode-component form than when the laser diode is integrated into an apparatus, and wherein the laser diode is configured to be integrated into the apparatus to direct light from the light-exit facet of the laser diode to a waveguide in the apparatus.
