Latest Patents

One of his latest patents is titled "Techniques for providing a swept wavelength (SW) measurement for acquiring polarization dependent loss (PDL) in a single scan." This invention involves a system that includes a tunable laser, a polarization element, and a power meter. The tunable laser emits an optical signal that sweeps across an optical band at a constant rate. The polarization element scrambles the polarization states of the optical signal, while the power meter takes measurements to determine the maximum and minimum insertion loss associated with the device-under-test (DUT). This allows for the calculation of average insertion loss and polarization dependent loss for the DUT.

Another significant patent is "Techniques for reducing optical ghosts in a gratings-based optical spectrum analyzer (OSA)." This invention features a monochromator apparatus that includes a diffraction grating and a rotatable oblique prism reflector element. The design aims to reduce or eliminate ghost effects caused by the grating element, thereby improving the resolution of optical measurements.
