Likamwa 1 , Gragory Salamo 2 , Demetrios N.Christodoulides 1 ; 1 University of Central Florida,CREOL, USA; 2 Department of Physics, Universityof Arkansas, USA. We report the experimental realizationof a non-Hermitian optical isolator basedon semiconductor nonlinear waveguide arrays.Such non-Hermitian isolators can in principle beintegrated on the same semiconductor platformalong with the laser source.CTu3F.3 • 17:15Silicon-on-Insulator Polarization Splitter-Rotator Based on TM0-TE1 Mode Conversion ina Bi-level Taper, Wesley Sacher 1 , Tymon Barwicz 2 ,Joyce K. Poon 1 ; 1 Electrical and Computer Engineering,University of Toronto, Canada; 2 IBM ThomasJ. Watson Research Center, USA. The first demonstrationof a silicon-on-insulator polarizationsplitter-rotator using TM0-TE1 mode conversionin a bi-level taper is reported. The device wasfabricated in a foundry process and and exhibitsa polarization crosstalk < -13 dB.CTu3G.4 • 17:15Generation of Programmable Passband ChirpedElectrical Pulses using Optical Interferometry,Amir Rashidinejad 1 , Andrew M. Weiner 1 ; 1 Electricaland Computer Engineering, Purdue University,USA. We present a novel optical interferometricstrategy to generate arbitrary linear/nonlinearfrequency-chirped electrical pulses with widelytunable center frequency. The Time-BandwidthProduct of these waveforms is twice that of currentcounterpart techniques.CTu3H.3 • 17:15Highly Multiplexed Dual-Comb Two-PhotonExcitation Spectroscopy, Arthur Hipke 1,2 ,Samuel A. Meek 1 , Theodor W. Hänsch 1,2 , NathaliePicqué 1,3 ; 1 Max-Planck-Institut für Quantenoptik,Germany; 2 Fakultät für Physik, Ludwig-Maximilians-UniversitätMünchen, Germany; 3 UniversitéParis-Sud, Institut des Sciences Moléculairesd’Orsay, CNRS, France. We present the latest resultsin extending dual-comb spectroscopy to twophotonresonances. By measuring two-photonexcitation of rubidium vapor and water-dissolvedfluorophores, we demonstrate both the high resolutionand speed of the technique.CTu3E.5 • 17:30Optical limiting and spectral stabilizationin segmented photonic lattices, MatthiasHeinrich 1,2 , Falk Eilenberger 2 , Roert Keil 2 , FelixDreisow 2 , Eric Suran 3 , Frédéric Louradour 3 ,Andreas Tünnermann 2 , Thomas Pertsch 2 , StefanNolte 2 , Alexander Szameit 2 ; 1 CREOL TheCollege of Optics and Photonics, University ofCentral Florida, USA; 2 Institute of Applied Physics,Friedrich-Schiller-University, Germany;3XLIM Institut de Recherche, CNRS-Universitéde Limoges, France. We demonstrate photoniclattices with segmentation-based linear self imagingas integrated optical limiters. The diffractivepropagation between input and output port offersthe additional benefit of substantially decreasednonlinear spectral distortionsCTu3E.6 • 17:45Second-order Nonlinear Processes using GapPlasmon-Polaritons, Jacob Khurgin 1 , GregorySun 2 ; 1 Johns Hopkins Univ., USA; 2 University ofMassachusetts Boston, USA. We show that usingmetal-insulator-metal (MIM) waveguides tocarry out various second-order nonlinear opticalprocesses not only provides highly desired tightoptical confinement but also facilitates the phasematchingdue to their inherently large anisotropy.CTu3F.4 • 17:30Athermal Silicon Ring Resonator with BimaterialCantilever for Passive Thermal Feedback,Biswajeet Guha 1 , Michal Lipson 1,2 ; 1 CornellUniversity, USA; 2 Kavli Institute at Cornell forNanoscience, USA. We demonstrate a temperatureinsensitive Si ring resonator by coupling the opticalmode to a bi-material cantilever. We show thecapability of athermal operation over 14 degrees,which can be further extended through properoptimization.CTu3F.5 • 17:45Silicon CWDM Demultiplexers Using Contra-Directional Couplers, Wei Shi 2,1 , Han Yun 1 ,Charlie Lin 1 , Xu Wang 1 , Jonas Flueckiger 1 , NicolasJaeger 1 , Lukas Chrostowski 1 ; 1 Electrical and ComputerEngineering, University of British Columbia,Canada; 2 Electrical and Computer Engineering,McGill University, Canada. We experimentallydemonstrate ultra-compact ( 50%.CTu3G.7 • 18:00Photonic Filtering for High-Frequency OptoelectronicOscillator Operation, Marcus Bagnell 1 ,Peter J. Delfyett 1 ; 1 University of Central Florida,CREOL, USA. A Fabry-Perot etalon with 1.498GHz free spectral range is used for photonic filteringin an optoelectronic oscillator. Oscillations atmultiples of its FSR are produced at 10.49 GHz,36.0 GHz, and 53.9 GHz.CTu3H.6 • 18:00Frequency-Agile, Rapid Scanning Spectroscopyfor Ultrasensitive Absorption Measurements,David Long 1 , Gar-Wing Truong 1,2 , Kevin O.Douglass 1 , Stephen E. Maxwell 1 , Roger D. vanZee 1 , David F. Plusquellic 1 , Joseph T. Hodges 1 ;1NIST, USA; 2 School of Physics, The University ofWestern Australia, Australia. We report a methodfor rapidly scanning a cw-laser through opticalcavity resonances. This technique involves amicrowave source and an electro-optic phasemodulator, giving high sensitivity, wide tunabilityand fast acquisition rates.Concurrent sessions are grouped across four pages.
