Abstract:
Described herein is a substrate including a central longitudinal axis, a first support web, and a second support web. A sinuous web may be positioned between the first support web and the second support web. The sinuous web may include transverse web portions and bridging web portions, where the bridging web portions alternatively connect ends of adjacent transverse web portions. The sinuous web may be connected to the first support web by support legs extending between bridging web portions and a surface of the first support web. The sinuous web may be connected to the second support web by support legs extending between bridging web portions and a surface of the second support web. A support leg length to distance between transverse web portions ratio may be from about 1.0 to about 4.0.
Abstract:
A ceramic waveguide includes: a doped metal oxide ceramic core layer; and at least one cladding layer comprising the metal oxide surrounding the core layer, such that the core layer includes an erbium dopant and at least one rare earth metal dopant being: lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, thulium, ytterbium, lutetium, scandium, or oxides thereof, or at least one non-rare earth metal dopant comprising zirconium or oxides thereof. Also included is a quantum memory including: at least one doped polycrystalline ceramic optical device with the ceramic waveguide and a method of fabricating the ceramic waveguide.
Abstract:
A quantum memory system includes a doped polycrystalline ceramic optical device, a magnetic field generation unit, and one or more pump lasers. The doped polycrystalline ceramic optical device is positioned within a magnetic field of the magnetic field generation unit when the magnetic field generation unit generates the magnetic field, the one or more pump lasers are optically coupled to the doped polycrystalline ceramic optical device, and the doped polycrystalline ceramic optical device is doped with a rare-earth element dopant that is uniformly distributed within a crystal lattice of the doped polycrystalline ceramic optical device.
Abstract:
A system, process and related sintered article are provided. The process includes supporting a piece of inorganic material with a pressurized gas and sintering the piece of inorganic material while supported by the pressurized gas by heating the piece of inorganic material to a temperature at or above a sintering temperature of the inorganic material such that the inorganic material is at least partially sintered forming the sintered article. The inorganic material is not in contact with a solid support during sintering. The sintered article, such as a ceramic article, is thin, has high surface quality, and/or has large surface areas.
