Latest Patents

One of his latest patents is titled "Nanoscale object detection using a whispering gallery mode resonator." This invention focuses on the detection of individual objects using a light source and a whispering gallery mode (WGM) resonator. The technology analyzes light from the WGM resonator to determine the presence of an object based on mode splitting associated with the light received by a photodetector. The presence of the object can be assessed by examining the distance between two whispering gallery modes or the linewidths of the two modes in a transmission spectrum. Additionally, it can be determined based on a beat frequency produced by combining split laser modes in the received light from a WGM microcavity laser.

Another significant patent is the "Miniaturized ultrafine particle sizer and monitor." This apparatus measures particle size distribution and includes a charging device and a precipitator. The charging device generates charged ions in response to an applied voltage, while the charger body creates a low energy electrical field to channel the charged ions. The design directs a flow of particles through the electrical field, allowing for precise measurement of particle sizes.
