We present a new technique of nonlineardual-comb spectroscopy for the measurementof coherent Stokes and anti-Stokes Ramanspectra of fundamental vibrational transitions.Ultra-rapid acquisition times, high-resolution,broad-spectral-span are the main characteristicsof our experiments.CTu3F.1 • 16:30 InvitedSub-100 μm Wide-Bandwidth Si PhotonicCrystal MZI Modulators, Hong C. Nguyen 1 ,Naoya Yazawa 1 , Satoshi Hashimoto 1 , ToshihikoBaba 1 ; 1 Yokohama National University, Japan. Wepresent sub-100 μm, error-free-capable Si photoniccrystal MZI modulators. The low-dispersionslow-light enables a 50 μm device with 12.5 nmoperational bandwidth, as well as 40 Gb/s-capable90 μm device.CTu3G.1 • 16:30Spatio-Temporal Focusing of UltrabroadbandWireless Signals Through Multipath ScatteringEnvironments, Amir Dezfooliyan 1 , Andrew M.Weiner 1 ; 1 Electrical and Computer Engineering,Purdue University, USA. We use photonic radiofrequencyarbitrary waveform generation for thefirst experimental demonstration of space-timecompression of ultra-broadband wireless signalsdistorted by highly scattering multipath channelsover a three octave frequency range of 2 to 18 GHz.CTu3H.1 • 16:30 InvitedRecent progress in high precision atmospherictrace gas instruments using Mid-infraredquantum cascade lasers, John B. McManus 1 ,Mark Zahniser 1 , David Nelson 1 , Ryan McGovern 1 ,Mike Agnese 1 ; 1 Aerodyne Research Inc, USA. Wereport results from high precision spectroscopicinstruments for atmospheric trace gases usingwith mid-IR quantum cascade lasers. Numerousgases can be measured with 1s absorption noise~1x10-6, allowing e.g. 1s OCS precision of 10-12.CTu3E.2 • 16:45Time-to-space conversion in a one dimensionalnonlinear waveguide, Dror Shayovitz 1 , HaraldHerrmann 2 , Wolfgang Sohler 2 , Raimund Ricken 2 ,Christine Silberhorn 2 , Dan M. Marom 1 ; 1 AppliedPhysics, Hebrew University of Jerusalem, Israel;2Applied Physics, University of Paderborn, Germany.We report the first demonstration of timeto-spaceconversion of sub-picosecond pulsesat 1.55μm in a nonlinear slab waveguide usingnon-degenerate, collinear SFG. A time window of46ps and serial-to-parallel demultiplexing factorof 93 were achieved.CTu3E.3 • 17:00Pulsed and CW IR Detection in Wide-gap Semiconductorsusing Extremely NondegenerateTwo-photon Absorption, Himansu S. Pattanaik 1 ,Dmitry A. Fishman 2 , Eric W. Van Stryland 1 , DavidJ. Hagan 1 ; 1 College of Optics & Photonics: CREOL& FPCE, University of Central Florida, CREOL,USA; 2 Department of Chemistry, Natural SciencesII, University of California, USA. We detect bothpulsed and CW IR light using uncooled GaN orGaAs photodiodes using extremely-nondegeneratetwo-photon-absorption (2PA) which shows largeenhancement over degenerate 2PA. Urbach-tailabsorption limits the signal-to-noise ratio forCW detection.CTu3F.2 • 17:00Large-Scale Optical Phased Arrays Enabled bySilicon Photonics, Jie Sun 1 , Erman Timurdogan 1 ,Ami Yaacobi 1 , Ehsan S. Hosseini 1 , Gerald Leake 2 ,Douglas D. Coolbaugh 2 , Michael R. Watts 1 ;1Electrical Engineering and Computer Science,Massachusetts Institute of Technology, USA; 2 Collegeof Nanoscale Science and Engineering, Universityat Albany, USA. The largest (up to 64×64) opticalphased arrays to date are demonstrated with siliconphotonics, including passive arrays generatingintricate far-field patterns and an active array fordynamic beam steering and shaping.CTu3G.2 • 16:45Compressed Multi-frequency RF Sensing withPhotonic Assistance, Yuyang Gao 1 , Yitang Dai 1 ,Kun Xu 1 , Li Yan 1 , Feifei Yin 1 , Jianqiang Li 1 , JintongLin 1 ; 1 Beijing University of Posts and Telecommunications,China.
