Latest Patents

One of her latest patents is a method for making an evanescent field coupler. This method involves preparing optical fibers by forming a groove along the top surface of a substrate block. The groove is designed to be shallower than the diameter of a stripped fiber. An optical fiber is positioned in the groove, with its center portion stripped of its coating. The optical fiber is then glued in the groove and polished to create a coupling region, while ensuring that the top surface of the substrate block remains unpolished. An optical signal is applied to one end of the optical fiber, and the loss of the optical signal is measured at the coupling region. The polishing and monitoring process is repeated until the desired loss value is achieved. This coupler can be integrated into an operating optical communication system.

Another patent she holds is for an evanescent field coupler itself. This invention comprises a coupler holder, a first optical fiber mounted in a first substrate block, and a second optical fiber mounted in a second substrate block. The first substrate block is compliantly mounted to the holder, and there are mechanisms for positioning the substrate blocks relative to each other for switching and adjusting the coupling ratio. The compliant mount allows for elastic deformation during switching and alignment, facilitating accurate and repeatable switching while maintaining the desired coupling ratio between the optical fibers.
