Journal ArticleDOI
Controlling photonic structures using optical forces
TL;DR: A resonant structure is implemented whose optical response can be efficiently statically controlled using relatively weak attractive and repulsive optical forces, and a static mechanical deformation of up to 20 nanometres in a silicon nitride structure is demonstrated, using three milliwatts of continuous optical power.
Journal ArticleDOI
Synchronization of micromechanical oscillators using light.
Mian Zhang,Gustavo S. Wiederhecker,Gustavo S. Wiederhecker,Sasikanth Manipatruni,Arthur Barnard,Paul L. McEuen,Michal Lipson +6 more
TL;DR: It is shown that the coupling between the two oscillators can be tuned continuously from uncoupled to maximally coupled, paving a path towards massive and long-range synchronized oscillator networks.
Journal ArticleDOI
Stimulated Brillouin scattering from multi-GHz-guided acoustic phonons in nanostructured photonic crystal fibres
Paulo Dainese,Paulo Dainese,P. St. J. Russell,Nicolas Joly,Jonathan Knight,Gustavo S. Wiederhecker,Hugo L. Fragnito,Vincent Laude,Abdelkrim Khelif +8 more
TL;DR: In this paper, the authors explore stimulated Brillouin scattering in photonic crystal fibres with subwavelength-scale solid silica glass cores and show that the spontaneous BrillouIN signal develops a highly unusual multi-peaked spectrum with Stokes frequency shifts in the 10 GHz range.
Journal ArticleDOI
Field enhancement within an optical fibre with a subwavelength air core
Gustavo S. Wiederhecker,Gustavo S. Wiederhecker,Cristiano M. B. Cordeiro,Cristiano M. B. Cordeiro,Francois Couny,Fetah Benabid,Stefan A. Maier,Jonathan Knight,Carlos Henrique de Brito Cruz,Hugo L. Fragnito +9 more
TL;DR: In this article, the authors demonstrate the concentration of optical energy within a subwavelength-scale air hole running down the length of a PCF core, which resembles a submicrometre-diameter tube with a bore diameter of 200nm or less.
Journal ArticleDOI
Models for guidance in kagome-structured hollow-core photonic crystal fibres.
TL;DR: It is demonstrated by numerical simulation that the general features of the loss spectrum of photonic crystal fibres (PCF) with a kagome structure can be explained by simple models consisting of thin concentric hexagons or rings of glass in air.
