At least one of the cavities is configured to receive a first material able to dissociate into one or more gases that are contained within the vapor cell. At least one of the cavities is configured to receive a second material able to absorb at least a portion of the one or more gases. The vapor cell could include a first cavity configured to receive the first material and a second cavity fluidly connected to the first cavity by at least one first channel, where the second cavity is configured to receive the gas(es).

Abstract: An integrated microfabricated sensor includes a sensor cell having a cell body, a first window attached to a first surface, and a second window attached to a second surface, opposite to the first window. The cell body laterally surrounds a cavity, so that the first window and the second window are exposed to the cavity. The sensor cell contains a sensor fluid material in the cavity. The cell body has recesses on opposing exterior sides of the cell body; each recess extends from the first surface to the second surface. Exterior portions of the cell body wall in the recesses are recessed from singulation surfaces on the cell body exterior. The cell body is formed by etching the cavity and the recesses concurrently through a body substrate. After the windows are attached, the sensor cell is singulated from the body substrate through the recesses.

Abstract: A magnetic sensor has a circuit segment with a quadrupole region. The quadrupole region includes a supply line, a first return line and a second return line, all in a conductor layer. The first supply line is laterally adjacent to the supply line on a first side, and the second return line is laterally adjacent to the supply line on a second, opposite side. A space between the supply line and the first return line is free of the conductor layer; similarly, a space between the supply line and the second return line is free of the conductor layer. The first return line and the second return line are electrically coupled to the supply line at a terminus of the circuit segment.

Abstract: An optoelectronic packaged device includes stacked components within a package including a package substrate providing side and a bottom wall. The stacked components includes a comb structure on the bottom wall formed from a material having a thermal resistance > a substrate material for the bottom die providing spaced apart teeth separated by gaps. The bottom die has a top surface including electrical trace(s) and a light source die for emitting light coupled to the electrical trace and a bottom surface on the comb structure. A first cavity die is on the top surface of the bottom die or on legs of the package which extend above the bottom wall. An optics die is on the first cavity die, a second cavity die is on a sealing die which is on the optics die, and a photodetector (PD) die is optically coupled to receive light from the light source die.

Abstract: A micro-fabricated atomic clock structure is thermally insulated so that the atomic clock structure can operate with very little power in an environment where the external temperature can drop to −40° C., while at the same time maintaining the temperature required for the proper operation of the VCSEL and the gas within the vapor cell.
