Abstract
Single-transverse-mode laser diodes that include a bowtie-shaped ridge waveguide. Related apparatuses, data storage devices, computing systems, and methods.
Claims20
A single-transverse-mode laser diode comprising a body, wherein the body comprises:
- an active region;
- a first facet;
- a second facet, wherein the first facet and second facet are on opposite ends of the body, wherein the second facet is the light-exit facet;
- and
- a bowtie-shaped ridge waveguide disposed in the body and configured to confine light generated in the active region and direct light toward the light-exit facet of the body, wherein the single-transverse-mode laser diode is configured to be coupled to an apparatus to communicate light from the light-exit facet of the single-transverse-mode laser diode to a near-field transducer in the apparatus.
