Abstract
This disclosure describes a red-green-blue (RGB) vertical-cavity surface-emitting laser (VCSEL) array. Each VCSEL in the VCSEL array has a grating, one or more active regions and two distributed Bragg reflectors. Each VCSEL corresponds to either red, green or blue wavelengths. The number of active regions in each VCSEL may be based on the color emitted.
Claims20
A system, the system comprising:
- an array of vertical-cavity surface-emitting lasers (VCSELs), wherein:
- the array of VCSELs comprises:
- at least one VCSEL operable to emit in a blue wavelength range,
- at least one VCSEL operable to emit in a green wavelength range, and
- at least one VCSEL operable to emit in a red wavelength range;
- and
- each VCSEL in the array of VCSELs comprises:
- an active region, and
- two distributed Bragg reflectors.
