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.

Score=730/1000 GOOD!
