Positions at Menlo Systems GmbH (MEN)
Applications are now welcomed for the QuRIOUS PhD position hosted by Menlo Systems (Munich)! To apply and find out more, please visit the Menlo website.
Objectives:
In this work package, MEN will work on the advancements of optical clock technology that does not rely on laser-cooled atoms. As compared to lattice clocks, such clocks provide an inferior performance, yet they come with vastly less complicated system designs and are, therefore, good candidates for commercialization in the near future. The focus of the project will be on the development of a clock based on hot rubidium vapor.
1) Feasibility of the envisioned Rb clock
Task 1: The DC will investigate the feasibility of a Rb clock in which the atoms are interrogated directly via heterodyne interference of frequency-doubled comb lines around 780 nm, hence reducing the need for an interrogation laser and related locking electronics in the system design. Task 2: Demonstrate proof-of-principle direct comb spectroscopy of hot Rb atoms in a breadboard model.
2) Development of the envisioned Rb clock
Task 3: After a successful proof-of-principle demonstration, the DC will work towards the development of an optical clock based on the aforementioned architecture. Target specifications will be defined from hot Rb clocks reported in literature and used to define requirements in terms of intensity stabilization, temperature stabilization and magnetic field shielding. Task 4: After clock integration, the stability of the clock will be characterized.
