Characterization of Electrothermal Actuation with Nanometer and Microradian Precision

June 21, 2015
Author(s)
Craig R. Copeland, Craig D. McGray, Jon C. Geist, Vladimir A. Aksyuk, Samuel M. Stavis
A recently introduced particle-tracking method was used to measure the single motion cycles of an electrothermal actuator with nanometer and microradian precision. Driving the actuator with a low-noise input induced deterministic motion that was perfectly

Small footprint nano-mechanical plasmonic phase modulators

June 21, 2015
Author(s)
Vladimir A. Aksyuk, Brian S. Dennis, Michael Haftel, David Czaplewski, Daniel Lopez, Girsh Blumberg
The authors’ recent Nature Photonics article titled “Compact Nano-Mechanical Plasmonic Phase Modulators” [1] is reviewed which reports a new phase modulation principle with experimental demonstration of a 23 μm long non-resonant modulator having 1.5 π rad

Compact Nano-Mechanical Plasmonic Phase Modulators

April 1, 2015
Author(s)
Brian S. Dennis, Michael Haftel, David Czaplewski, Daniel Lopez, Girsh Blumberg, Vladimir Aksyuk
The miniaturization of photonic devices is fundamentally limited by the index of refraction of the constituent materials if light is confined in dielectric nanostructures. By coupling electromagnetic fields to metal's free electrons plasmonic devices

Near-Field Asymmetries in Plasmonic Resonators

February 12, 2015
Author(s)
Vladimir Aksyuk, Basudev Lahiri, Glenn Holland, Andrea Centrone
Surface-enhanced infrared absorption (SEIRA) spectroscopy exploits the locally enhanced field surrounding plasmonic metamaterials to increase the sensitivity of infrared spectroscopy. Light polarization and incident angle are important factors for exciting

Strong Casimir force reduction by metallic surface nanostructuring

September 27, 2013
Author(s)
Francesco Intravaia, Stefan T. Koev, Il Woong Jung, Albert A. Talin, Paul S. Davids, Ricardo Decca, Vladimir Aksyuk, Diego A. Dalvit, Daniel Lopez
The Casimir force is a quantum-mechanical interaction arising from vacuum fluctuations of the electromagnetic (EM) field and is technologically significant in micro- and nanomechanical systems. Despite rapid progress in nanophotonics, the goal of

Silicon Micromachines for Fun and Profit

December 12, 2012
Author(s)
David Bishop, Flavio Pardo, Cris Bolle, Randy Giles, Vladimir Aksyuk
Over the last decade or so a group of us, while working at Bell Labs, have been able to develop a large number of silicon micromachines for a wide range of applications. In this article, which is part of a special volume to celebrate the career of

Giant piezoelectricity in PMN-PT thin films: Beyond PZT

November 1, 2012
Author(s)
S. H. Baek, M. S. Rzchowski, Vladimir Aksyuk
Micro-electromechanical systems (MEMS) incorporating piezoelectric layers provide active transduction between electrical and mechanical energy, which enables highly sensitive sensors and low-voltage driven actuators surpassing the passive operation of

Quasianalytical modal approach for computing Casimir interactions in periodic nanostructures

October 3, 2012
Author(s)
Francesco Intravaia, Paul S. Davids, Ricardo Decca, Vladimir Aksyuk, Daniel Lopez, Diego A. Dalvit
We present an almost fully analytical technique for computing Casimir interactions between 1D periodic lamellar gratings based on a modal approach. Our method improves on previous work on Casimir modal approaches for nanostructures by using the exact form
