Patent number: 11557872Abstract: Fiber optic amplification includes a photonic crystal fiber coupled to a pump laser through a first coupler. The pump laser emits a first electromagnetic radiation wave into the photonic crystal fiber at a first oscillation frequency and a second electromagnetic radiation wave into the photonic crystal fiber at a second oscillation frequency equaling the first oscillation frequency. The first and second electromagnetic radiation waves interact to generate a signal comprising an electromagnetic radiation wave at a third oscillation frequency and an idler comprising a fourth electromagnetic radiation wave at a fourth oscillation frequency to be generated and amplified through parametric amplification. Parametric amplification is achieved by four wave mixing. The photonic crystal fiber emits a parametric output signal based on the four wave mixing. A nonlinear crystal frequency doubles the parametric output signal through second-harmonic generation.Type: GrantFiled: August 20, 2019Date of Patent: January 17, 2023Assignee: The Government of the United States of America, as represented by the Secretary of the NavyInventors: L.

Publication number: 20170307782Abstract: The present invention provides a specific gradient-optical-index porous (GRIP) layer coating on inorganic optical substrate surfaces, and the fabrication method used to create the GRIP layer coating. The method consists of two major processing steps: (1) the co-deposition of an optical index-matching material and a mass density-modulating material, followed by (2) the sacrificial etch of the mass-density-modulating material to reveal a GRIP surface. The method is designed for use with crystalline, polycrystalline, and dry or wet etch-resistant substrate materials, where anti-reflective (AR) solutions using AR surface structures (ARSSs) do not exist. These coatings are designed to minimize Fresnel reflectivity of the original substrate surfaces, using a single porous layer matched to the optical index of the original substrate material.Type: ApplicationFiled: April 21, 2017Publication date: October 26, 2017Inventors: Menelaos K.
