Abstract
Summary form only given. One simple approach to achieve cascade laser diodes is to lithographically series connect individual devices. We report the first lithographic cascade VCSEL arrays which exhibit > 100% differential quantum efficiency. We present measurements of the light output into a broad area detector versus injection current into the cascade VCSEL arrays. The output power increases approximately linearly with the number of array elements, and arrays with 4 or more VCSELs exhibit > 100% differential quantum efficiency. These initial results indicate that lithographic cascade VCSEL arrays show promise for low cost optical links.
