Abstract
An organic vertical cavity laser light producing device includes a bottom dielectric stack reflective to light over a predetermined range of wavelengths; an organic active region for producing laser light, and having an organic active region including emissive material; and a top dielectric stack spaced from the bottom dielectric stack and reflective to light over a predetermined range of wavelengths. Pump-beam light is transmitted and introduced into the organic active region through at least one of the dielectric stacks. The organic active region includes one or more periodic gain region(s) and organic spacer layers disposed on either side of the periodic gain region(s) and arranged so that the periodic gain region(s) is aligned with the antinodes of the device's standing wave electromagnetic field, and wherein the spacer layers are substantially transparent to the laser light.
