Latest Patents

Chi Au's latest patents include an "Optical isolator, attenuator and polarizer system and method for integrated optics." This innovative optical system features a first branch that allows light to pass in both forward and reverse directions, utilizing a medium with a specific refractive index. The design includes a second branch that permits light to pass only in the forward direction, ensuring that light traveling in reverse does not interfere with the second branch. This configuration is crucial for maintaining the integrity of optical signals.

Another significant patent involves "All optical logic using cross-phase modulation amplifiers and Mach-Zehnder interferometers with phase-shift devices." This invention constructs optical logic gates from Mach-Zehnder Interferometer circuits, where a multi-mode interference splitter divides input light into two branches. The use of semiconductor optical amplifiers enables cross-phase modulation, resulting in phase shifts that facilitate logic operations. The combination of these branches leads to destructive interference, producing a logic low output.
