Title: Innovations of John Hoose
Introduction
John Hoose is a notable inventor based in Fairport, NY (US), recognized for his contributions to optical communication technologies. With a total of nine patents to his name, he has made significant advancements in the field of diffractive structures and grating devices.
Latest Patents
One of his latest patents is a three-dimensional diffractive structure, which includes a method for making and applications thereof. This three-dimensional grating device features two crossed diffraction gratings that exhibit diffraction efficiency substantially independent of the incident polarization within an optical communication spectral window from 1.5-1.6 μm. The gratings are characterized by different periods in two directions, chosen to support only one dispersive diffraction order in addition to the zero (specular) order. Exemplary grating profiles include sinusoidal and truncated pyramidal (trapezoidal) profiles. This invention provides a method for diffracting polarization-independent light with 90% or higher efficiency, with applications in various wavelength control devices particularly useful in telecommunications.
Another significant patent is a grating device with an adjusting layer. This reflection grating device incorporates a continuous non-reflecting dielectric adjusting layer situated between a grating structure and one or more continuous reflecting layers. It operates efficiently in an order of interest, such as the first or third order of diffraction, while minimizing unwanted orders. Such devices are applicable in telecommunication and laser applications.
