Latest Patents

One of Haesler's latest patents is an advanced atomic clock. This invention proposes a new atomic clock design that includes at least one light source for providing an optical beam, a photo detector, and a vapor cell with a first optical window. The optical beam is directed through the vapor cell to generate an optical frequency reference signal. The photo detector detects this signal and generates a reference signal. Notably, the atomic clock features a first optical waveguide that incouples a portion of the optical beam, expanding the guided light beam. The thickness of the atomic clock is less than 15 nm, showcasing a remarkable miniaturization of technology.

Another significant patent is the micro-machined vapor cell. This invention consists of a central silicon element that forms a cavity containing vapor cell reactants, such as alkali metals or alkali metal azides, along with buffer gases and anti-relaxation coatings. The cavity is sealed with first and second glass caps, and a solenoid is arranged to provide a homogeneous magnetic field to the vapor cell. This solenoid is coiled directly on the central silicon element, representing a substantial improvement in the development of highly miniaturized atomic clocks.
