US Patent:

20220206359, Jun 30, 2022

Filed:

Dec 29, 2021

Appl. No.:

17/564302

Inventors:

- State College PA, US
Douglas E. WOLFE - State College PA, US

Assignee:

HAMR Industries LLC - State College PA

International Classification:

G02F 1/35

Abstract:

An optical filter includes a substrate; a first mirror on the substrate; a cavity layer on the first mirror; and a second mirror on the cavity layer. Each of the first and second mirrors provide high reflection, low transmission and low absorption over a targeted stopband. The cavity layer defines a resonant transmission band within the targeted stopband with the resonant band wavelength depending on the optical thickness of the cavity layer. The cavity layer includes a material having a non-linear response to incident irradiance such that cavity absorption changes with irradiance and suppresses cavity resonance at high irradiance. The material having the non-linear response to the incident irradiance includes a two-dimensional (2D) material.

Filed:

Jun 30, 2010

Appl. No.:

12/827811

Inventors:

Joshua A. Robinson - Spring Mills PA, US
Douglas E. Wolfe - St. Marys PA, US

Assignee:

THE PENN STATE RESEARCH FOUNDATION - UNIVERSITY PARK PA

International Classification:

G01T 3/08

US Classification:

25037005, 250371

Abstract:

The present invention provides an innovative solid-state neutron detector that exhibits superior neutron-sensitivities. One embodiment of the present invention includes a Gadolinium-oxide (GdO)-based neutron detector that is highly sensitive to the presence of neutrons, and experiences significant changes in film conductivity, capacitance or both as a result of thermal neutron exposure thereby providing for detection of nuclear radiation.
