Microlens-integrated 980 nm vertical-cavity surface-emitting lasers (VCSELs) were fabricated and their mode-stabilized operations investigated. A stable single fundamental transverse mode operation in the microlens-integrated VCSEL was observed. Numerical modal calculations accurately explain the effects of the microlens on mode stabilization.

Key words: vertical-cavity surface-emitting laser (VCSEL), microlens, mode stabilization, single mode, fundamental transverse mode
