Title: Innovations of Yin Zhang in Optical Technology
Introduction
Yin Zhang is a prominent inventor based in San Jose, California, known for her significant contributions to optical technology. With a total of eight patents to her name, she has made remarkable advancements in the field of wavelength division multiplexing (WDM) systems.
Latest Patents
Among her latest patents is the Optical Add/Drop Module, which features a WDM add/drop module. The drop portion of this module utilizes thin film filters or thin film interleavers. The add portion employs fused fiber interleavers for the less critical stages of the multiplexing process. In the final stage, fused fiber interleavers can be placed in series. Additionally, a thin film interleaver with a flattop frequency response may be used for the critical stage, where the multiplexed channels are more closely spaced. This design ensures that the frequency response of the thin film interleaver remains relatively constant across the bandwidth of a channel while minimizing cross talk at the channel edges.
Another notable patent is the Thin Film Interleaver, which includes thin film optics. This device is designed to reflect one group of wavelengths while allowing a second group to pass through. The thin films are engineered to exhibit a flat top frequency response across the channel bandwidths of the multiplexed signal, making the thin film interleaver less sensitive to wavelength drift and temperature variations.
