Latest Patents

Dar-Yuan Song's latest patents showcase his ability to blend innovative design with engineering precision. The first patent is a **Tunable Filter for Optical Add/Drop Module**. This tunable filter consists of a polarizing beam splitter and a half-wave plate that convert an arbitrarily polarized input light into two equally polarized beams. These beams are directed towards a specialized tunable component—an optical substrate coated with a filter. The innovative design ensures that the filter's performance remains independent of polarization, eliminating issues related to channel shifting during tuning.

The second notable patent is for the **Optical Path Length Tuner**. This device employs a parallel glass plate mounted on a rotating fixture to control the optical path length of a light beam accurately. It allows for precise adjustments to the optical path as a function of the angle of incidence, achieving nanometer-level precision. This invention is particularly useful for fine-tuning cavity lengths in resonators or optical path differences in interferometers.
