Title: Mark H Berry: Innovator in Optical Technology
Introduction
Mark H Berry is a notable inventor based in El Cajon, California. He has made significant contributions to the field of optical technology, holding a total of 3 patents. His work primarily focuses on advancements in differential amplifiers and optical switching systems.
Latest Patents
One of his latest patents is the "Wide Bandwidth Differential Amplifier." This innovative device is designed for gigahertz bandwidth electrical signals using fiber optics and integrated optical devices. It features a differential gain that is influenced by the electrical to optical and optical to electrical conversion factors. The common mode rejection ratio of this differential amplifier at 1 GHz exceeds 30 dB, and it varies based on the time difference between the differential amplifier inputs. This technology has potential applications in radar and communications systems.
Another significant patent is the "High Speed Serial Optical Crossbar Switch." This optical crossbar switch consists of multiple input integrated optical couplers connected to a star coupler at one end of an optical cable. It also includes a star coupler at the other end, which connects to several output integrated optical couplers. The system allows discrete parallel optical input signals to be fed to each input integrated optical switch, with clock signals facilitating a time division multiplexed switching sequence. This design ensures the efficient transfer of multiple signals while minimizing losses associated with conventional spatial light modulator interconnections.
