Claim 10:
11. A method of manufacturing an LED device, the method comprising:
forming an n-type current spreading layer on a substrate;
forming at least one photoluminescent quantum well on the n-type current spreading layer;
forming an n-type layer on the at least one photoluminescent quantum well;
forming at least one electroluminescent quantum well on the n-type layer;
forming a p-type layer on the electroluminescent quantum well;
etching to form a first mesa and a second mesa separated by a trench, the trench having at least one side wall and extending to the n-type current spreading layer;
conformally depositing a dielectric layer on the first mesa and the second mesa;
forming a contact hole in the first mesa and the second mesa; and
forming a first contact on the first mesa and a second contact on the second mesa.
