Latest Patents

One of Cashen's latest patents is for a photonic chip-based atomic sensor. This invention describes an atomic sensor that includes a photonic die capable of outputting optical signals on its top surface. These optical signals can be directed and shaped to meet the specific requirements of different types of atomic sensors. In one embodiment, an atomic source, such as rubidium or cesium, is placed on the photonic chip to emit atoms when heated. A collimator is then used to direct the emitted atoms along a path that intersects with the optical signals, allowing for the detection of motion, including rotation and acceleration, of the atomic sensor.

Another significant patent by Cashen involves a collimated atomic beam source featuring a source tube with an openable seal. This invention includes various embodiments of collimated beam atomic ovens and methods for loading a source of atoms into an atomic oven. An illustrative collimated beam atomic oven consists of a tube with a first and second portion, a source of atoms in the first portion, an aperture in the second portion
