Abstract
In a general aspect, a system for generating radio frequency (RF) electromagnetic radiation includes a maser having a photonic crystal structure and a vapor. The photonic crystal structure is formed of dielectric material and includes an array of cavities having a defect region disposed therein and an elongated slot disposed in the defect region. The array of cavities and the elongated slot define a waveguide having a waveguide mode. The vapor is disposed in the elongated slot and includes one or more input electronic transitions and an output electronic transition coupled to the one or more input electronic transitions. The output electronic transition is operable to emit a target RF electromagnetic radiation and is resonant with the waveguide mode. The system also includes a laser system configured to provide input optical signals to the elongated slot and signal processing electronics in communication with the laser system.
