Design of a doubly-clamped beam structure capable of localizing mechanical and optical energy at the nanoscale is presented. The optical design is based upon photonic crystal concepts in which patterning of a nanoscale-cross-section beam can result in strong optical localization to an effective optical mode volume of 0.2 cubic wavelengths (λ c) 3.

—Progress on the development of a frequency chain devoted to the absolute frequency measurement of 127 I 2-stabilized lasers around 563.2 THz/532 nm is reported. The aim of this work is the improvement of the accuracy—by at least one order of mag-nitude—of the absolute frequency of this standard. The scheme is based on the frequency combination of two(More)
