Latest Patents
Kwang Nam Kang's latest patents include the "All-optical XOR gate by using semiconductor optical amplifiers." This invention relates to a method of embodying an all-optical XOR logic gate utilizing the cross-gain modulation (XGM) characteristic of semiconductor optical amplifiers. The technique allows for the control of the logic gate through input currents, illumination signals, and pumping signals. The operational characteristics are achieved by inputting pump and illumination signals concurrently into two semiconductor optical amplifiers, summing the output signals that exhibit XGM characteristics due to gain saturation and wavelength conversion.
Another notable patent is the "Method and apparatus for silicon fusion bonding of silicon substrates." This method involves bonding silicon substrates in a wet oxygen atmosphere. The process includes stabilizing the silicon substrates, primarily bonding them, and heat-treating them at high temperatures to eliminate micro-gaps at the junction interface. The apparatus designed for this method features a hollow quartz tub, a flask for providing the wet oxygen atmosphere, a heater, and a movable carrier for handling the silicon substrates during the bonding process.
