Abstract
An approach to achieve cascade laser diodes is to lithographically series connect individual devices is presented. As such, vertical cavity surface emitting lasers (VCSELs) are particularly amenable to this since close packed 2-dimensional arrays are demonstrated. Moreover high volume/low cost VCSEL manufacture implies that low cost analog optical link with gain could be feasible. This paper reports on the first lithographic cascade VCSEL arrays which exhibit > 100% differential quantum efficiency.
