Abstract
An organic vertical cavity laser light producing device (10) comprises a substrate (20). A plurality of laser emitters (200) emits laser light in a direction orthogonal to the substrate. Each laser emitter within the plurality of laser emitters has a first lateral mode structure in a first axis orthogonal to the laser light direction and has a second lateral mode structure in a second axis orthogonal to both the laser light direction and the first axis. Each laser emitter comprises a first mirror provided on a top surface of the substrate (20) and is reflective to light over a predetermined range of wavelengths. An organic active region (40) produces laser light (350). A second mirror is provided above the organic active region and is reflective to light over a predetermined range of wavelengths. A pumping means excites the plurality of laser emitters.
