Abstract:
1. A vertical cavity surface emitting laser comprising: a first mirror region forming a first distributed Bragg reflector; a first cladding region positioned on the first mirror region; an active region positioned on the first cladding region; a second cladding region positioned on the active region and including a high electrical resistance implanted region positioned to define a current path; a second mirror region positioned on the second cladding region; a current spreading region positioned an the second mirror region; a first electrical contact in electrical communication with the current spreading region and a second electrical contact positioned to conduct electrical current in circuit with the first electrical contact through the current path; the current spreading region and the second mirror region cooperating to produce substantially uniform current distribution in the current path, the current spreading region having an index guide formed therein; and a third mirror region positioned on the current spreading region, the second and third mirror regions cooperating to produce a complete distributed Bragg reflector.
