Title: Innovations of Luca Dal Negro
Introduction
Luca Dal Negro is a prominent inventor based in Cambridge, MA (US), known for his significant contributions to the field of optical technologies. With a total of 12 patents, he has made remarkable advancements that have implications in various applications, particularly in illumination devices and optical elements.
Latest Patents
One of his latest patents is titled "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.
Another notable patent is "Diffractive axilenses and uses thereof." This optical element includes a substrate and a pattern, where the substrate has a top surface and a bottom surface. The pattern is provided on the top surface and includes multiple levels, ensuring that the thickness of the pattern is less than a design wavelength. The pattern is designed to focus incident radiation received at either surface of the substrate at one or more prescribed focal locations on a detection plane. The focal locations change in proportion to the wavelength of the incident radiation, making the detection plane an achromatic focal plane when the incident radiation includes multiple wavelengths.
