Title: David J M Stothard: Innovator in Parametric Devices and Coatings

Introduction

David J M Stothard is a notable inventor based in Fife, GB. He has made significant contributions to the field of parametric devices and coatings, holding two patents that showcase his innovative spirit and technical expertise.

Latest Patents

Stothard's latest patents include "Parametric generation using intersecting cavities" and "Coating for optimising output coupling of em radiation." The first patent describes a parametric device that utilizes a non-linear material to generate an idler wave and a signal wave in response to a pump wave. This device features a cavity resonant at the pump wavelength and mechanisms for varying the angle between the propagation directions of the pump and idler waves. The second patent focuses on a coating that is placed between a nonlinear crystal and a silicon prism coupler. This coating effectively prevents the transmission of radiation scattered within the crystal by filtering out frequencies outside the silicon bandgap, thereby avoiding free carrier absorption while allowing THz frequencies that correspond to the bandgap to pass through.
