Latest Patents

Clark's latest patents include groundbreaking work on optical elements designed to improve phase functions. The first patent, titled "Phase-transforming optical element formed by partial etching or by partial etching with reflow," describes an optical element that incorporates a transmissive layer made up of discrete volumes of first and second optical media. These volumes are strategically arranged to approximate a desired phase function, which is essential for providing a range of phase delays. The patent emphasizes the importance of effecting partial reflow of the optical media to reduce unwanted diffraction or scattering.

The second patent, "Phase-transforming optical reflector formed by partial etching or by partial etching with reflow," focuses on a reflective optical element featuring a reflective surface with a multitude of recessed and non-recessed areas. Similar to the first patent, these areas are arranged to approximate a desired phase function and are smaller than the operational wavelength. This design also aims to smooth the morphology of the reflective surface through partial reflow, thereby minimizing unwanted diffraction or scattering.
