Abstract: An assembly includes one or more high temperature vapor cells positioned along an axis of the assembly, a vacuum envelope encasing the one or more high temperature vapor cells, and one or more sets of low thermal conductivity mounting structures coupled to the vacuum envelope. Each set of low thermal conductivity mounting structures is configured to position a corresponding one of the high temperature vapor cells within the vacuum envelope.

Abstract: A sensor comprising a vapor cell including a vapor of alkali atoms is disclosed. The sensor further comprises a first photonic integrated circuit (PIC) configured to direct light of a first wavelength into the vapor cell and incident on the vapor of alkali atoms, wherein the light of the first wavelength is configured to excite the alkali atoms to a first excited state from a ground state. The sensor further comprises a detector configured to detect a response of the alkali atoms, after the alkali atoms are excited from the first excited state to a Rydberg state, to incident electromagnetic radiation.

Abstract: The disclosure describes vacuum cell assemblies that integrate a vacuum envelope with a photonic integrated circuit (PIC). Walls of the vacuum envelope are coupled to the PIC, such as through anodic bonding, so that the PIC forms at least one wall of the vacuum envelope and provides an optically accessible medium and surface for transmitting and distributing light into various cavities of the vacuum envelope through one or more nonplanar waveguides. A surface of the PIC may include a material that is compatible with a material of the walls of the vacuum envelope, such as a silicon-based vacuum envelope bonded to a silicon nitride or amorphous silicon surface of the PIC. Each waveguide may include a bridge structure that forms a planar surface for tightly bonding with the vacuum envelope and preserves properties of the transmitted light between opposing sections of the waveguide.

Abstract: The disclosure includes an outer electrode and an inner electrode. The outer electrode defines an inner volume and is configured to receive injected electrons through at least one aperture. The inner electrode positioned in the inner volume. The outer electrode and inner electrode are configured to confine the received electrons in orbits around the inner electrode in response to an electric potential between the outer electrode and the inner electrode. The apparatus does not include a component configured to generate an electron-confining magnetic field.
