Patent number: 11953765Abstract: A method is provided for operating one or more one solid-state electro-optic device to provide an electrically switching shutter. The method includes forming an alternating stack of first semiconductor layers having a first dopant and second semiconductor layers having a second dopant to form at least one superlattice semiconductor device. The method further includes applying to the at least one superlattice semiconductor device a first voltage to induce a transparent state of the alternating stack such that light is transmitted through the alternating stack, and applying to the at least one superlattice semiconductor device a second voltage different from the first voltage to induce an opaque state of the alternating stack such that light is inhibited from passing through the alternating stack.Type: GrantFiled: April 10, 2023Date of Patent: April 9, 2024Assignee: RAYTHEON COMPANYInventors: Jamal I.

Patent number: 10777959Abstract: This disclosure provides planar waveguides with enhanced support and/or cooling. One or more endcaps could be disposed between coating/cladding layers at one or more ends of a core region, where the core region is doped with at least one active ion species and each endcap is not doped with any active ion species that creates substantial absorption at pump and signal wavelengths. A core region could include at least one crystal or crystalline material, and at least one cladding layer could include at least one glass. Different types of coolers could be disposed on or adjacent to different coating/cladding layers. Side claddings could be disposed on opposite sides of a planar waveguide, where the opposite sides represent longer sides of the waveguide. Endcaps and one or more coolers could be sealed to a housing, and coolant can flow through a substantially linear passageway along a length of the waveguide. One side of a planar waveguide could be uncooled.Type: GrantFiled: November 29, 2017Date of Patent: September 15, 2020Assignee: Raytheon CompanyInventors: Stephen H. McGanty, David M.
