Abstract:
1. An organic vertical cavity laser light producing device, comprising: a) a bottom dielectric stack reflective to light over a predetermined range of wavelengths; b) an organic active layer for producing laser light, comprising an emissive material that has a host material; c) a top dielectric stack spaced from the bottom dielectric stack and reflective to light over a predetermined range of wavelengths; d) an external pump-beam light structure for producing light that is transmitted and introduced into the organic active region through at least one of the dielectric stacks wherein the absorption of the host material significantly overlaps the emission spectrum of the pump-beam light; and e) the organic active layer is positioned between the bottom and top dielectric stacks and includes one or more periodic gain layers and organic spacer layers disposed on either side of the periodic gain layer(s) and arranged so that the periodic gain layer(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.
