Patent 7606499 was granted and assigned to Massachusetts Institute of Technology on October, 2009 by the United States Patent and Trademark Office.
A bidirectional transceiver assembly includes a VCSEL structure that emits light at a defined wavelength on a substrate structure. A photodetector receives the light. A hole structure is formed on the substrate structure to allow the light from the VCSEL structure to be emitted so as to form an optical path.
