Organic vertical cavity laser and imaging system

Today's pick up in organic semiconductor patents.

Organic vertical cavity laser and imaging system.

AndrewF. Kurtz, MarekW. Kowarz, BrianE. Kruschwitz and KeithB. Kahen

Eastman Kodak Company

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.
