Abstract
An electrically-pumped vertical-cavity surface-emitting laser (VCSEL) has multiple active regions. Embodiments of the invention provide an electrically-pumped VCSEL having a number of different p-i-n junction and electrode arrangements, which, in various embodiments, allow independent biasing of the multiple active regions, and, in other embodiments, allow simplified electrical connections.
