摘要: Metalenses and technologies incorporating the same are disclosed. In some embodiments, the metalenses are in the form of a hybrid multiregion collimating metalens that includes a first region and a second region, wherein the hybrid multiregion collimating metalens is configured to collimate (e.g., visible) light incident thereon. In some instances the first region includes an array of first unit cells that contain subwavelength spaced nanostructures, such that the first region functions as a subwavelength high contrast grating (SWHCG), whereas the second region includes an array of second unit cell, wherein the array of second unit cells includes a near periodic annular arrangement of nanostructures such that the second region approximates the functionality of a locally periodic radial diffraction grating. Lighting devices including such metalenses are also disclosed.

摘要: A broadly tunable single-mode infrared laser source based on semiconductor lasers. The laser source has two parts: an array of closely-spaced DFB QCLs (or other semiconductor lasers) and a controller that can switch each of the individual lasers in the array on and off, set current for each of the lasers and, and control the temperature of the lasers in the array. The device can be used in portable broadband sensors to simultaneously detect a large number of compounds including chemical and biological agents. A microelectronic controller is combined with an array of individually-addressed DFB QCLs with slightly different DFB grating periods fabricated on the same broadband (or multiple wavelengths) QCL material.

摘要: A method of fabricating a visible spectrum optical component includes: providing a substrate; forming a resist layer over a surface of the substrate; patterning the resist layer to form a patterned resist layer defining openings exposing portions of the surface of the substrate; performing deposition to form a dielectric film over the patterned resist layer and over the exposed portions of the surface of the substrate, wherein a top surface of the dielectric film is above a top surface of the patterned resist layer; removing a top portion of the dielectric film to expose the top surface of the patterned resist layer and top surfaces of dielectric units within the openings of the patterned resist layer; and removing the patterned resist layer to retain the dielectric units over the substrate.
