Abstract
In some implementations, an optical system may include an optical emitter configured to emit a beam, wherein the optical emitter is a vertical cavity surface emitting laser (VCSEL), and wherein the VCSEL is a top-emitting VCSEL or a bottom-emitting VCSEL. The optical system may include a liquid crystal component, the liquid crystal component being disposed on a surface of the optical emitter. The optical system may include a control component.
Claims20
An optical system, comprising:
- an optical emitter configured to emit a beam,
- wherein the optical emitter is a vertical cavity surface emitting laser (VCSEL),
- wherein the VCSEL is a top-emitting VCSEL or a bottom-emitting VCSEL;
- a liquid crystal component,
- the liquid crystal component being disposed on a surface of the optical emitter;
- and
- a control component.

A vertical cavity surface emitting laser (VCSEL) assembly, comprising:
- a VCSEL,
- wherein the VCSEL includes a substrate,
- a bottom distributed Bragg reflector (DBR) disposed on the substrate,
- an active region, and
- a top DBR, wherein the bottom DBR and the top DBR sandwich the active region;
- and
- an integrated liquid crystal cell disposed on the top DBR to control a polarization of light emitted from the VCSEL.
4 more elements
A method, comprising:
- receiving, by a controller, an input;
- generating, by the controller, a control signal;
- and
- outputting, by the controller, the control signal to a control component of an optical system,
- the control component being configured to control an orientation of molecules within a liquid crystal component disposed on a surface of an optical emitter of the optical system,
- a polarization state of light emitted by the optical system being based on the orientation of the molecules within the liquid crystal component.
