J.Kippenberg 1,2 ; 1 Max-Planck-Inst. of QuantumOptics, Germany, 2 École Polytechnique Fédérale deLausanne, Switzerland. We show that evanescentfields of microresonators can be employed forcavity-enhanced high-sensitivity monitoringof nanomechanical motion. This novel schemeopens the path to observing backaction effectsusing optical gradient forces in the resolvedsidebandregime.Monday, June 1CMW2 • 2:00 p.m.Nonlinear Femtosecond Pulse Propagationin All-Solid Photonic Bandgap Fiber, TadeuszMartynkien 1 , Bertrand Kibler 2 , Christophe Finot 2 ,Julien Fatome 2 , Marcin Szpulak 1 , Jan Wojcik 3 , StefanWabnitz 2 , Waclaw Urbanczyk 1 ; 1 Wroclaw Univ. ofTechnology, Poland, 2 Inst. Carnot de Bourgogne,France, 3 Maria Curie-Sklodowska Univ., Poland.Nonlinear femtosecond pulse propagation inall-solid photonic bandgap fiber is investigatedexperimentally and numerically for both thephotonic bandgap guiding in the central silicacore and the total internal reflection in germaniumdoped inclusions.Daniel R. Grischkowsky is a Regents Professorand the Bellmon Professor of Optoelectronicsat Oklahoma State University. He received hisPh.D. in physics from Columbia University in1968. He then joined the IBM Watson ResearchCenter, where he developed THz time-domainspectroscopy (THz-TDS). In 1993 he relocated toOSU. He is a Fellow of APS, OSA and IEEE. Hewas awarded the Boris Pregel Award for AppliedScience and Technology (1985) by the New YorkAcademy of Sciences, the R.W. Wood Prize fromOSA (1989), and the William F. Meggers Awardfrom OSA (2003).CMY2 • 2:00 p.m.Precision Spectroscopy with a Scanning DiodeLaser and Measurement of Microcavity Dispersion,Pascal Del’Haye 1 , Olivier Arcizet 1 , RonaldHolzwarth 1 , Tobias Kippenberg 1,2 ; 1 Max-Planck-Inst.for Quantum Optics, Germany, 2 École PolytechniqueFédérale de Lausanne, Switzerland. We present asimple method that enables fast, broadband spectroscopyat sub-Megahertz resolution over >4 THzbandwidth using a mode-hop-free tunable diodelaser and a frequency comb.

Westudy coupling between light and nano-particlesuspensions, through surface-tension effects incapillaries. Increasing light intensity far-awayfrom the interface causes huge changes in the fluidlevel, manifesting optical control over mechanicalproperties of fluids.IMG3 • 2:00 p.m.Three-Dimensional Super-Resolution Single-Molecule Fluorescence Imaging Using a Double-Helix Point Spread Function, Michael A. Thompson1 , Sri Rama Prasanna Pavani 2 , Julie S. Biteen 1 ,Rafael Piestun 2 , W. E. Moerner 1 ; 1 Stanford Univ.,USA, 2 Univ. of Colorado at Boulder, USA.
