Abstract
A method of forming a vertical cavity surface emitting laser (VCSEL) device using a multiphase growth sequence includes forming a first mirror over a substrate; forming an active region (e.g., a dilute nitride active region) over the first mirror; forming an oxidation aperture (OA) layer over the active region; forming a spacer on a surface of the OA layer; and forming a second mirror over the spacer. The active region is formed using a molecular beam epitaxy (MBE) process during an MBE phase of the multiphase growth sequence and the second mirror is formed using a metal-organic chemical vapor deposition (MOCVD) process during an MOCVD phase of the multiphase growth sequence.
