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.
Claims9
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;
- 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 then the interpixel regions so that the array emits coherent phase-locked laser light;
- and
- e) wherein the active region includes one or more periodic gain region(s) and organic spacer layers disposed on either side of the periodic gain region(s) and arranged so that the periodic gain region(s) is aligned with the antinodes of the device's standing wave electromagnetic field.
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 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.
