Abstract
A vertical cavity surface emitting laser (VCSEL) of types otherwise known is provided with integrated electronics. The integrated electronics may be, for example, transistors. Other electronic elements may also be integrally formed with the VCSEL. Also integrally formed with the VCSEL may be a detector for detecting light emitted by the VCSEL. The electronics and/or detector may be of hydrogenated amorphous silicon (a-Si:H). The detector may have transparent contacts, of for example of indium tin oxide (ITO), formed by techniques otherwise known. Improved, on-chip addressing is possible, and improved detector architecture is provided.
