Room 315 Room 316 Room 317IQECCLEOIME • Solitons and NonlinearWave Propagation—ContinuedCMO • Free Space Optical andQuantum Communications—ContinuedCMP • Resonant and PhotonicCrystal Structures Emission—ContinuedIME5 • 11:15 a.m.Soliton Emission from a Trapping Potential,Marco Peccianti 1,2 , Gaetano Assanto 2 ; 1 Res. Ctr.SOFT INFM-CNR, “Sapienza” Univ., Italy, 2 NonlinearOptics and OptoElectronics Lab (NooEL),Univ. “Roma Tre”, Italy. Spatial solitons trapped in aconfining potential can undergo power dependentscattering. As the potential depends on the nonlinearity,solitons can accumulate transverse accelerationand eventually escape. We demonstrated thisphenomenon in a reorientational medium.CMP4 • 11:15 a.m.High Efficient and Tunable Edge EmittingMicrolaser on Photonic Crystal Slab, WanhuaZheng, Mingxin Xing, Wei Chen, Wenjun Zhou,Anjin Liu, Hailing Wang, Lianghui Chen; Inst. ofSemiconductors, CAS, China. Tunable edge emittingmicrolaser was realized with a line defectwaveguide, in which the radii of holes adjacent tothe defect was varied gradually. A tunable rangeof 17 nm was obtained experimentally.IME6 • 11:30 a.m.Nonlinear Self-Focusing of Partially-CoherentSpatial Beams, Can Sun, Dmitry V. Dylov, JasonW. Fleischer; Princeton Univ., USA. We consider thepropagation of a partially-coherent spatial beam inboth self-focusing and self-defocusing nonlinearmedia. Measurements of beam widths for bothnonlinearities confirm theoretical predictionsbased on a nonlinear Gaussian-Schell model.IME7 • 11:45 a.m.Observation of Two-Dimensional Quasi-LocalizedSolitons with Saddle-Shaped Diffractionand Hybrid Nonlinearity, Yi Hu 1 , Cibo Lou 1 ,Peng Zhang 1,2,3 , Sheng Liu 2 , Jianlin Zhao 2 , JingjunXu 1 , Jianke Yang 4 , Zhigang Chen 1,3 ; 1 Nankai Univ.,China, 2 Northwestern Polytechnical Univ., China,3San Francisco State Univ., USA, 4 Univ. of Vermont,USA. We report the first demonstration of 2-Dquasi-localized solitons near a saddle point ofdiffraction surfaces. These solitons arise from abalance between saddle-shaped diffraction andhybrid nonlinearity in optically-induced ionictypephotonic lattices.Prof. Nicolas Gisin was born in 1952 in Geneva,Switzerland were he studied physics and mathematics.He received his Ph.D. in Physics fromthe University of Geneva in 1981. The “FondationLouis de Broglie” recognised his dissertation withan award. After a post-doc at the University ofRochester, NY, he worked for a start-up companydedicated to fibre instrumentation. In 1988 hejoined the Group of Applied Physics at the Universityof Geneva as head of the optics section.Under his leadership the optics section developedthree research directions: telecom, optical sensorsand quantum optics. The telecom and the sensingactivities led to many patents and technologicaltransfers to Swiss and international industries,with several commercial successes. The quantumoptics activities are orientated towards fundamentalresearch. Quantum cryptography and longdistance quantum entanglement received a lot ofattention from the international scientific communityas well as from the mass media. In 2003,this was recognised as one of the 10 technologiesthat should “change the world “!CMP5 • 11:30 a.m.Stable Circularly-Polarized Emission from Vertical-CavitySurface-Emitting Lasers, Fan Zhang,Chunfeng Zhang, Jian Xu, Akhlesh Lakhtakia; PennState Univ., USA. A vertical cavity surface emittinglaser (VCSEL) comprising a polarization-selectivechiral reflector was designed, fabricated, andtested.
