  • Method of varying a characteristic of an optical vertical cavity structure formed by metalorganic vapor phase epitaxy
    Patent number: 6258615
    Abstract: A process for forming an array of vertical cavity optical resonant structures wherein the structures in the array have different detection or emission wavelengths. The process uses selective area growth (SAG) in conjunction with annular masks of differing dimensions to control the thickness and chemical composition of the materials in the optical cavities in conjunction with a metalorganic vapor phase epitaxy (MOVPE) process to build these arrays.
