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.
