Latest Patents

One of his latest patents is titled "Memory cell comprising coupled Josephson junctions." This invention discloses methods and apparatus for operating a memory cell formed from a plurality of coupled Josephson junctions. The memory cell is designed so that applying an electrical signal to the junctions can cause at least one, but not all, of the junctions to change their respective phase states. Subsequent writes to the memory cell using substantially the same electrical pulse do not alter the phase state of the plurality of junctions. The memory cell can be read by providing another electrical pulse to one of the junctions and receiving an output electrical pulse generated in response by a different Josephson junction of the memory cell. A set of phase states is selected to represent the logic values that remain stable across anticipated operating conditions for the memory cell. Additionally, methods of selecting electrical parameters and manufacturing memory cells are further disclosed.

Another significant patent is for "V-shaped resonators for addition of broad-area laser diode arrays." This system and method describe the addition of broad-area semiconductor laser diode arrays. The system includes an array of laser diodes, a V-shaped external cavity, and grating systems to provide feedback for phase-locking of the laser diode array. A V-shaped mirror is utilized to couple the laser diode emissions along two optical paths, which can be a V-shaped prism mirror, a V-shaped stepped mirror, or include multiple V-shaped micro-mirrors. The V-shaped external cavity can be a ring cavity, and the system may also include an external injection laser to further improve coherence and phase-locking.
