Abstract
Micromirrors were fabricated in gallium phosphide by mass transport to prov ide spatial-mode control of vertical-cavity surface-emitting lasers (VCSEL' s). The concave mirrors were used in an external-cavity configuration to pr ovide spatial filtering in the far field. Single-mode cw lasing was demonst rated in 15-mu m-diameter VCSEL's with currents as high as 6 times threshol d. The fabrication process was extended to micromirrors in gallium arsenide by use of a replication and dry-etch transfer process. (C) 1999 Optical So ciety of America.
