Latest Patents

One of her latest patents is for a broad bandwidth, single mode fiber optic coupler and method. This invention provides a fiber optic coupler formed by a length of two optic fibers, where the first fiber has a different core diameter than the second. The fibers are twisted at both ends, with a central portion where they are fused parallel to each other. This design allows an input light signal to be split into output light signals in a predetermined power ratio, making the coupled power ratio relatively insensitive to a range of signal wavelengths. Another notable patent is for 1XN and NXN fiber optic couplers, which utilize at least three optic fibers arranged in a linear array. This innovative design allows for varying coupling coefficients among the fibers, enabling repeatable manufacturing of various fiber couplers with consistent power ratios.
