Latest Patents

One of Di Yang's latest patents is a "Tunable single-channel dispersion compensator for high-speed optical systems." This invention includes a plurality of first optical elements and a second optical element that are optically coupled in a cascaded fashion. Each first optical element has a group delay response characterized by a first period, allowing only one group delay peak within a first channel. In contrast, the second optical element has a group delay response characterized by a second period, which is shorter than the first period, resulting in multiple group delay peaks within the same channel. This design utilizes cascaded GT etalons to achieve the desired group delay responses, increasing the passband of the dispersion compensator without raising insertion losses.

Another notable patent is the "Method and apparatus for a fiber optic housing and aligning device." This invention presents an apparatus and method for a fiber optic housing and aligning device. It features a housing with an opening in a wall that has a curved surface, along with a tubular casing that includes a ring with a matching curved surface. This design allows for directional adjustment of the casing relative to the housing, with a collimator positioned within the casing. The ring and wall are designed to be permanently fixed together, enhancing the stability and functionality of the device.
