Abstract
A white-light laser integrated structure that includes a substrate; and one or more individually addressable laser light pixels formed on the substrate for emitting a white beam of laser light perpendicular to the substrate. Each of the one or more individually addressable laser light pixels include one or more organic light emitting diodes (OLEDs) and a plurality of organic vertical cavity lasers that are arranged to be optically pumped by the one or more OLEDs. The plurality of organic vertical cavity lasers emits differently colored light and the one or more individually addressable laser light pixels emit substantially white light when the differently colored light is combined.

A white-light laser integrated structure comprising:
- a) a substrate;
- and
- b) one or more individually addressable laser light pixels formed on the substrate for emitting a white beam of laser light perpendicular to the substrate, each of the one or more individually addressable laser light pixels include one or more organic light emitting diodes (OLEDs) and a plurality of organic vertical cavity lasers that are arranged to be optically pumped by the one or more OLEDs, wherein the plurality of organic vertical cavity lasers emit differently colored light and the one or more individually addressable laser light emitting pixels emit substantially white light when the differently colored light is combined.
A polarized white-light laser, comprising:
- a) a substrate;
- and
- b) one or more individually addressable laser light pixels formed on the substrate for emitting a white beam of laser light perpendicular to the substrate, each of the one or more individually addressable laser light pixels include one or more organic light emitting diodes (OLEDs) and a plurality of organic vertical cavity lasers, having an asymmetric shape and producing polarized light, that are arranged to be optically pumped by the one or more OLEDs, wherein the plurality of organic vertical cavity lasers emit differently colored light and the one or more individually addressable laser light pixels emit substantially white light when the differently colored light is combined.
A system for producing an array of image elements forming a collimated beam of patterned white-light, comprising:
- a) a controller and connections;
- b) a plurality of individually addressable laser light pixels formed on a common substrate responsive to the controller for producing the array of image elements;
- and
- c) each of the plurality of individually addressable laser light pixels include one or more organic light emitting diodes (OLEDs) and a plurality of organic vertical cavity lasers that are arranged to be optically pumped by the one or more OLEDs, wherein the plurality of organic vertical cavity lasers emit differently colored light perpendicular to the substrate and the plurality of individually addressable laser light pixels emit substantially white light when the differently colored light is combined.
A method for creating a white-light laser comprising the steps of:
- a) providing a substrate;
- and
- b) forming one or more individually addressable laser light pixels on the substrate, wherein each of the one or more individually addressable laser light pixels include one or more organic light emitting diodes (OLEDs) and a plurality of spatially distributed organic vertical cavity lasers for emitting a white beam of laser light perpendicular to the substrate from a plurality of different colored light emitted from the plurality of spatially distributed organic vertical cavity lasers.
