LTCC integrated miniature Rb discharge lamp module for stable optical pumping in miniature atomic clocks and magnetometers

Herbert Shea, Peter Ryser, Thomas Maeder, Fabrizio Vecchio, Vinu Lalgudi Venkatraman

We report here on an integrated mini-lamp module (15x26x4 mm3) with a microfabricated rf-powered Rb dielectric barrier discharge (DBD) lamp (10x10x3 mm3) positioned on top of a 0.6 mm thick (thickness adjustable) 4-layer LTCC (Low Temperature Co-fired Cera ...

Dispensing and Hermetic Sealing Rb in a Miniature Reference Cell for Integrated Atomic Clocks

Herbert Shea, Peter Ryser, Thomas Maeder, Fabrizio Vecchio, Vinu Lalgudi Venkatraman

An innovative method for filling and sealing the reference cell for a Rubidium (Rb) integrated atomic clock is presented. We used a simple, low-temperature solder sealing technique for producing mini-cells of the size of 12 x 10 x 2 mm, suitable for Rb min ...
