Abstract
We have fabricated arrays of top-emitting VCSELs with pitches down to 24 mum and an only 2 mum wide gap between the devices. For enhanced single-mode emission, the inverted surface relief technique was applied on some devices. The output facets then contain a shallow, circular etch in their center.
