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.
