Latest Patents

One of his latest patents is the "Compact Tunable Optical Time Delay." This invention features a compact design that applies dispersion-free time delay to input optical signals. It includes an optical subassembly and a mechanical subassembly that allows for tuning the delay using a linear actuator. The design minimizes optical misalignment during the tuning process, making it both self-contained and cost-effective. The device maintains its exterior dimensions while allowing for interior motion, and it supports both reflection-type and transmission-type optical time delays.

Another significant patent is the "Optical Isolators." This device minimizes polarization mode dispersion and consists of a first polarization splitter/combiner, a non-reciprocal polarization rotator, and a second polarization splitter/combiner. It allows only forward propagation of light while blocking backward optical signals. The optical paths are arranged to achieve equal lengths, effectively minimizing polarization mode dispersion and polarization dependent loss.
