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.

Abstract: In a general aspect, a vapor cell includes a body defined by a stack of layers bonded to each other. The stack of layers includes a first end layer disposed at a first end of the body and a second end layer disposed at a second, opposite end of the body. Intermediate layers extend between the first and second end layers and define an internal cavity extending through the body between the first end layer and the second end layer. The stack of layers also includes first and second sets of tabs. The first set of tabs extends outward from the intermediate layers on a first exterior side of the body, and the second set of tabs extends outward from the intermediate layers on a second exterior side of the body. The vapor cell also includes a vapor or a source of the vapor disposed in the internal cavity.

Abstract: In a general aspect, a photonic crystal maser includes a dielectric body having an array of cavities ordered periodically to define a photonic crystal structure in the dielectric body. The dielectric body also includes a region in the array of cavities defining a defect in the photonic crystal structure. An elongated slot through the region extends from a slot opening in a surface of the dielectric body at least partially through the dielectric body. The array of cavities and the elongated slot define a waveguide having a waveguide mode. The photonic crystal maser also includes a vapor or source of the vapor in the elongated slot and a laser configured to generate an optical signal capable of exciting one or more input electronic transitions of the vapor.
