Latest Patents

Ran Zhang holds a patent for an "Aperiodic nano-optical array for angular shaping of incoherent emissions." This invention discloses a number of dielectric pillars arranged to form a close-packed aperiodic array, such as a Vogel spiral. The geometries of this aperiodic array produce azimuthally isotropic scattering of luminescence within a restricted angular cone of extraction. The aperiodic array can be formed, attached, or placed on a converting material, such as phosphor, to restrict emission to within the angular cone of extraction. This phosphor could be part of a converting illumination device, such as a phosphor-coated light-emitting diode or a laser-activated remote phosphor converting device.
