Abstract

Microlenses and microlens arrays made from Group III-nitride material.

Claims (25)

1. A microlens, comprising a refractive property and a primary microlens material, wherein the continuous phase of the primary microlens material comprises a ternary or a quaternary alloy of a Group III-nitride.

2. The microlens of claim 1 , wherein the microlens exhibits transmissivity to electromagnetic radiation.

3. The microlens of claim 1 , wherein the microlens is transmissive to light within the green to blue spectrum.

4. The microlens of claim 1 , wherein the microlens is transmissive to ultraviolet light.

5. The microlens of claim 1 , wherein the microlens is substantially integratable with nitride-based opto-electronic devices.

6. A system, comprising:

an opto-electronic device; and

at least one microlens according to claim 1 .

7. The system of claim 6 , wherein said opto-electronic device comprises nitride-based material.

8. The system of claim 6 , wherein said opto-electronic device comprises Group III nitride-based material.

9. The microlens of claim 1 , wherein the microlens is formed of a nitride material comprising Al, Ga, and N.

10. The microlens of claim 1 , wherein the microlens is formed of a nitride material comprising In, Ga, and N.

11. A microlens array, comprising at least one microlens according to claim 1 .

12. The microlens of claim 1 , wherein the microlens comprises one or more epilayers of the ternary or the quaternary alloy of a Group III-nitride.

13. The microlens of claim 6 , wherein the microlens comprises one or more epilayers of the ternary or the quaternary alloy of a Group III-nitride.

14. A microlens, comprising a refractive property and a primary microlens material, wherein the continuous phase of the primary microlens material comprises InN or alloys thereof, and wherein the microlens comprises one or more epitaxially grown epilayers of InN or alloys thereof.

15. A microlens array, comprising at least one microlens according to claim 14 .

16. A system, comprising:

an opto-electronic device; and

at least one microlens according to claim 14 .

17. A microlens, comprising a refractive property and a primary microlens material, wherein the continuous phase of the primary microlens material comprises AlN or alloys thereof, and wherein the microlens comprises one or more epitaxially grown epilayers of AlN or alloys thereof.

18. A microlens array, comprising at least one microlens according to claim 17 .

19. A system, comprising:

an opto-electronic device; and

at least one microlens according to claim 18 .
