Latest Patents
Cifelli holds a patent for a "High dispersion diffraction grating including multiple holographic optical elements." This invention features a diffraction grating that incorporates multiple holographic optical elements (HOEs), including a Dickson grating and at least one other volume phase grating (VPG). The design aims to provide high dispersion, uniform diffraction efficiency, and equal diffraction efficiencies for all polarizations across a wide range of wavelengths. The refractive index modulations of the Dickson grating's volume phase medium have significantly greater spatial frequency than those of each other VPG in the multi-HOE grating. This technology can be manufactured at low cost and is particularly useful in Dense Wavelength Division Multiplexing (DWDM) applications.
