Latest Patents

One of her latest patents is titled "Temperature insensitive Mach-Zehnder interferometers and devices." This invention features a Mach-Zehnder interferometer that includes two optical couplers interconnected by two optical fibers, with at least one being temperature insensitive. The design allows for temperature-induced changes in the geometrical length and refractive index of the fibers to offset each other, ensuring that the optical path length remains unaffected by temperature changes. This interferometer can be utilized in Dense Wavelength Division Multiplex systems.

Another notable patent is the "Method and apparatus for frequency tuning of an unbalanced Mach-Zehnder interferometer." This invention introduces a novel method to adjust the MZ filter channels to align with the ITU grid. By inducing an optical path length difference using a UV light source, the refractive index of the fiber arms can be altered after the device is packaged. This method allows for a weaker UV source power and shorter treatment times, minimizing the risk of localized fiber damage.
