Abstract
An organic vertical cavity phase-locked laser array device includes 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 an etched region formed in a surface of the bottom dielectric stack to define an array of spaced laser pixels which have higher reflectance than the interpixel regions so that the array emits coherent phase-locked laser light.
Claims10
An organic vertical cavity laser array device, comprising:
- a) a bottom dielectric stack reflective to light over a predetermined range of wavelengths;
- b) an organic active region for producing laser light;
- c) a top dielectric stack spaced from the bottom dielectric stack and reflective to light over a predetermined range of wavelengths;
- and
- d) an etched region formed in a surface of the bottom dielectric stack to define an array of spaced laser pixels which have higher reflectance than the interpixel regions so that the array emits coherent phase-locked laser light.
An organic vertical cavity laser array device, comprising:
- a) a first dielectric stack reflective to light over a predetermined range of wavelengths;
- b) an organic active region for producing laser light;
- c) a second metallic layer spaced from the first dielectric stack and reflective to light;
- and
- d) an etched region formed in a surface of the first dielectric stack to define an array of spaced laser pixels which have higher reflectance than the interpixel regions so that the array emits coherent phase-locked laser light.
