OPTICAL WAVEFORM SAMPLING OF A 320 GBIT/S SERIAL DATA SIGNAL USING A HYDROGENATED AMORPHOUS SILICON WAVEGUIDE
Hua Ji1, Hao Hu1, Minhao Pu1, Michael Galili1, Palle Jeppesen1, Bart Kuyken2, Shankar Kumar Selvaraja2, Geert Morthier2, Roel G. Baets2, Leif K. Oxenlowe1; 1DTU Fotonik, Technical University of Denmark, Denmark; 2Photonics Research Group, INTEC Department, Gent University, Belgium.
 We propose using a hydrogenated amorphous silicon waveguide for ultra-high-speed serial data waveform sampling. 320 Gbit/s serial optical data sampling is experimentally demonstrated with +12 dB intrinsic four wave mixing conversion efficiency.

NON-DEGENERATE FOUR-WAVE MIXING IN A SILICON NANOWIRE AND ITS APPLICATION FOR ONE-TO-SIX WDM MULTICASTING
Minhao Pu1, Hao Hu1, Hua Ji1, Michael Galili1, Leif K. Oxenlowe1, Kresten Yvind1, Palle Jeppesen1, Jørn M. Hvam1; 1DTU Fotonik, Photonics Engineering, Technical Univ. of Denmark, Denmark.
We present WDM multicasting based on non-degenerate four-wave mixing in a silicon nanowire. A one-to-six phase-preserving wavelength multicasting of 10 Gb/s differential phase-shift-keying data is experimentally demonstrated with bit-error rate measurements.

Bart Kuyken1, Xiaoping Liu2, Stephane Clemmen3, Shankar Kumar Selvaraja1, Wim Bogaerts1, Dries Van Thourhout1, Richard M. Osgood2, Philippe Emplit3, Serge Massar3, Yurii A. Vlasov4, William M. Green4, Gunther Roelkens1, Roel G. Baets1; 1University of Ghent, Belgium; 2Columbia University, USA; 3Université Libre de Bruxelles, Belgium; 4IBM T. J. Watson Research Center, USA.
Silicon nanowires have an immense potential for nonlinear optical functions. Recent work on four-wave-mixing gain in hydrogenated amorphous silicon wires at telecom wavelengths and in crystalline silicon wires in the 2µm wavelength range is reviewed.

HIGH-SPEED AND LOW-ENERGY FLIP-FLOP OPERATION OF ASYMMETRIC ACTIVE-MULTIMODE INTERFEROMETER BI-STABLE LASER DIODES
Haisong Jiang1, Yutaka Chaen1, Takuma Hagio1, Kazuisao Tsuruda1, Makoto Jizodo1, Shinji Matsuo2, Jing Xu3, Christophe Peucheret3, Kiichi Hamamoto1; 1Interdisciplinary Graduate School of Engineering Sciences, Kyushu University, Japan; 2NTT photonics laboratories, Japan; 3Photonics Engineering, Technical University of Denmark, Denmark.
High-speed (121/25 ps rise/fall time) and low-switching energy (7.1 and 3.4 fJ) all-optical flip-flop operation of single-wavelength high-mesa asymmetric active-MMI bi-stable laser diodes is demonstrated for the first time using 25 ps long switching pulses.

WAVELENGTH CONVERSION FOR 1.2TB/S OPTICAL OFDM SIGNAL BASED ON FOUR-WAVE MIXING IN HNLF WITH DIGITAL COHERENT DETECTION
Ze Dong2,3, Jianjun Yu1; 1ZTE USA, ZTE USA, USA; 2Georgia Institute of Technology, USA; 3Hunan University, China.
Orthogonal dual-pump polarization insensitive wavelength conversion based on four-wave mixing of 1.2 Tb/s optical OFDM signal in high-nonlinear optical fiber is proposed and experimentally demonstrated for the first time. The converted signal is coherent detected and OSNR penalty is around 2 dB after wavelength conversion.

Isabelle Cestier1, Amnon Willinger1, Pierre Colman2, Sylvain Combrie2, Gaelle Lehoucq2, Alfredo De Rossi2, Gad Eisenstein1; 1Electrical Engineering, Technion, Israel; 2Thales Research and Development, France.
We report 1.3dB parametric gain, a 2% four wave mixing conversion efficiency and ~25% pulse compression in a W1 GaInP photonic crystal waveguide fed by 32ps, 415mW pump pulses and a 700 uW CW probe signal.
