Abstract
An organic vertical cavity phase-locked laser array device includes a substrate, a bottom dielectric stack reflective to light over a predetermined range of wavelengths, and an organic active region for producing laser light. The device also includes a top dielectric stack spaced from the bottom dielectric stack and reflective to light over a predetermined range of wavelengths, and a patterned reflectance modulator formed on a surface of the substrate to define an array of spaced laser pixels which have higher reflectance than the interpixel regions and causes the array to emit coherent phase-locked laser light.
Claims13
An organic vertical cavity laser array device, comprising:
- a) a substrate;
- b) a patterned reflectance modulator defining pixel and interpixel regions and being disposed over the substrate;
- c) a bottom dielectric stack disposed over the patterned reflectance modulator and being reflective to light over a predetermined range of wavelengths;
- d) an organic active region disposed over the bottom dielectric stack for producing laser light;
- and
- e) a top dielectric stack spaced from the bottom dielectric stack and reflective to light over a predetermined range of wavelengths so that an array of spaced laser pixels is defined, which have higher reflectance than the interpixel regions and causes the array to emit coherent phase-locked laser light.
