Abstract

Selectively oxidized monolithic vertical cavity surface emitting lasers (VCSEL) with various oxide aperture configurations are grown by metallorganic vapor phase epitaxy. VCSEL samples with 20 top distributed Bragg reflectors (DBR) periods and oxide apertures overlapping field nulls or antinodes on single or double apertures of the optical cavity are compared. VCSELs with tapered 3/4-λ thick apertures emit a single transverse mode over the entire operation for single or double apertures overlapping field nulls or antinodes while VCSELs with single nontapered 30 nm thick oxide aperture operate a single mode only ≤3 μm dia. VCSELs. Reduced optical confinement and optical loss are produced and efficient electrical confinement is maintained.
