Latest Patents

One of his latest patents is the "All-optical timing jitter measurement system and method." This innovative system acquires timing jitter in an all-optical manner by extracting the timing jitter probability distribution function using auto-correlation and cross-correlation data. This method is particularly beneficial for ultra-high bit rates, where traditional power spectrum analysis is not applicable. The resolution of this measurement system surpasses the actual pulse width and is dependent on the correlator's time resolution. This invention aids in identifying both deterministic and random timing jitters, providing valuable feedback for actively controlling timing jitter within optical networks.

Another notable patent is the "Integrated spectral encoder/decoder for optical CDMA communication system." This design utilizes waveguide circuits that are monolithically integrated on a single chip to perform essential encoding and decoding functions. The device operates as a 1×2 wavelength selective Mach-Zehnder interferometer switch, encoding the input broadband light source and decoding the transmitted spectrally encoded signals. It includes a frontal 3-dB coupler, a double-ended arrayed-waveguide grating (AWG), and arrays of thermo-optic phase shifters and attenuators. These components work together to achieve programmable encoding and decoding capabilities, enhancing the performance of optical CDMA systems.
