Latest Patents
One of her latest patents is focused on controlled dopant diffusion for fiber optic couplers. This innovation improves the uniformity of optical coupling in elements such as couplers and splitters. The process involves heat treatment that causes dopants in the core of an optical fiber to diffuse into the material from the cladding layer. This results in a substantially homogeneous interior region of the optical element. The increased lossiness of the optical element can be limited by terminating the heat treatment before dopant diffusion reaches equilibrium. This ensures that a portion of the cladding layer remains surrounding the homogeneous region where the fibers are fused together. The method allows for highly repeatable and regulated dopant diffusion, providing selective, wavelength-dependent coupling between fibers, which is particularly useful for multiplexing and demultiplexing applications.
