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 a top dielectric stack spaced from the bottom dielectric stack and reflective to light over a predetermined range of wavelengths. The device also includes the active region in which is contained 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.
Claims6
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 region for producing laser light;
- c) a top dielectric stack spaced from the bottom dielectric stack and reflective to light over a predetermined range of wavelengths;
