ALEXANDRIA, Va., July 3 -- United States Patent no. 12,349,486, issued on July 1, was assigned to Aeluma Inc. (Goleta, Calif.).

"Photodetector module comprising emitter and receiver" was invented by Jonathan Klamkin (Goleta, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Techniques for realizing compound semiconductor (CS) optoelectronic devices on silicon (Si) substrates are disclosed. The integration platform is based on heteroepitaxy of CS materials and device structures on Si by direct heteroepitaxy on planar Si substrates or by selective area heteroepitaxy on dielectric patterned Si substrates. Following deposition of the CS device structures, device fabrication steps can be carried out using Si ...
