ABSTRACT:
Using ion implant isolation, applicant has demonstrated a substantially planar quantum well photodetector free of exposed mesa side walls and having performance characteristics comparable with conventional mesa QWIPs. The planar photodetector presents a topography well suited for integration with other electronic components and the planar structure can be scaled to diameters much smaller than are typically useful in the conventional bonded devices.
