Counting the cycles of light using a self-referenced optical microresonator

Tobias Kippenberg, Tobias Herr, Martin Hubert Peter Pfeiffer, Victor Brasch, John David Jost, Caroline Marie Anne Lecaplain

Phase coherently linking optical-to-radio frequencies with femtosecond mode-locked laser frequency combs has enabled counting the cycles of light and is the basis of optical clocks, absolute frequency synthesis, tests of fundamental physics, and improved s ...

Compact High-Performance Continuous-Wave Double-Resonance Rubidium Standard With 1.4 x 10(-13) tau(-1/2) Stability

Anja Skrivervik, Francesco Merli, Camillo Stefanucci

We present our studies on a compact high-performance continuous wave (CW) double-resonance (DR) rubidium frequency standard in view of future portable applications. Our clock exhibits a short-term stability of 1.4 x 10(-13) tau(-1/2), consistent with the s ...

Integrated packaging solutions and hotplates for a miniature atomic clock and other microsystems

Fabrizio Vecchio

This thesis aimed at developing innovative packaging solutions for a miniature atomic clock and other microsystems in the cm-scale, i.e. somewhat larger than what is practical for full "chip-scale" device-package integration using clean-room technologies f ...

Low Temperature Hermetic Wafer Bonding and Microfabrication of Wall-Coated Alkali Vapor Cells for Chip-Scale Atomic Clocks

Rahel Strässle

The increasing demand for highly precise, yet compact and low power timing devices pushes the research in the field of chip scale atomic clocks (CSACs). At the heart of a CSAC, there is a vapor cell containing a few micrograms of alkali metal, such as rubi ...

An Enhanced Design Methodology for Resonant Clock Trees

Giovanni De Micheli, Vasileios Pavlidis, Somayyeh Rahimian Omam, Xifan Tang

Clock distribution networks consume a considerable portion of the power dissipated by synchronous circuits. In conventional clock distribution networks, clock buffers are inserted to retain signal integrity along the long interconnects, which, in turn, sig ...
