Abstract: Vapor cells are disclosed that include a dielectric body having a first surface and a second surface. The dielectric body includes a plurality of walls extending from the first surface to the second surface. A perimeter wall surrounds an open volume of the dielectric body and interconnected walls are arranged within the open volume to partition the open volume into a plurality of cells. Each cell has a first opening defined by the first surface and a second opening defined by the second surface. The vapor cells additionally include a first optical window covering the first openings and having a surface bonded to the first surface of the dielectric body to form a seal around each of the first openings.

Abstract: In a general aspect, electromagnetic emissions from a cell tower are measured. In some aspects, a method includes receiving, at a vapor-cell sensor system associated with the cell tower, electromagnetic radiation from an antenna system disposed on the cell tower. The method includes receiving, at the vapor-cell sensor system, input optical signals communicated from a laser system through respective input optical channels. Output optical signals are generated in the vapor-cell sensor system based on the input optical signals and the electromagnetic radiation. The method additionally includes sending, from the vapor-cell sensor system, the output optical signals through one or more respective output optical channels to a detection system. Systems for measuring electromagnetic emissions from a cell tower are also presented.

Abstract: In a general aspect, a system is described herein for detecting the phase properties of a radio frequency (RF) wave. The system includes a vapor cell sensor that contains a vapor and is configured to generate an optical signal in response to laser signals that interact with the vapor. The vapor has a Rydberg electronic transition that interacts with a target RF electromagnetic field, and the optical signal is based on a transmission of one of the laser signals through the vapor. The system also includes an optical detection system and a signal processing system. The optical detection system is configured to generate a detector signal in response to receiving the optical signal, and the signal processing system is configured to receive the detector signal and perform operations that determine a phase change of the target RF electromagnetic field.

Abstract: In a general aspect, a radiometer is disclosed that includes a vapor cell sensor. The vapor cell sensor contains a vapor and is configured to generate an optical signal in response to laser signals and thermal radiation interacting with the vapor. The vapor includes a Rydberg electronic transition that is configured to interact with the thermal radiation. The radiometer also includes a computing system having one or more processors and a memory. The memory stores instructions that, when executed by the one or more processors, are configured to perform operations that include generating, based on the optical signal, transmission data that represents the transmission of the one laser signal through the vapor. The operations also include determining, based on the transmission data, a temperature of a target body that generates the thermal radiation.

Abstract: In a general aspect, a communication system comprises a first station and a second station. The first station includes a photonic crystal maser, a laser subsystem, and a tracking subsystem. A photonic crystal structure of the photonic crystal maser is formed of dielectric material and has an array of cavities and an elongated slot. The elongated slot is disposed in a defect region of the array of cavities. The photonic crystal maser also includes a vapor disposed in the elongated slot and operable to emit a target RF electromagnetic radiation in response to receiving an optical signal. The array of cavities and the elongated slot define a waveguide configured to form the target RF electromagnetic radiation, when emitted, into a beam. The second station includes a receiver configured to couple to the beam of target RF electromagnetic radiation.
