Abstract
A vapor cell includes an interrogation cell in a substrate, the interrogation cell having an entrance window and an exit window, and a first transparent thin-film heater in thermal communication with the entrance window. The transparent thin-film heater has a first layer in communication with a first pole contact at a proximal end of the heater and a layer coupler contact at a distal end, a second layer in communication with a second pole contact at the proximal end, and the second layer electrically coupled to the layer coupler contact at the distal end. An insulating layer is sandwiched between the first and second layers. The insulating layer has an opening at the distal end to admit the layer coupler contact and to insulate the remainder of the second layer from the first layer. The first and second pole contacts are available to complete an electric circuit at the proximal end, with magnetic fields for each of the first and second layers oriented in opposing directions when a current is applied through the circuit.
