320-GB/S WAVELENGTH CONVERSION BASED ON CROSS-GAIN MODULATION IN A QUANTUM-DOT SOA

1COBRA Research Institute, Eindhoven University of Technology, Netherlands; 2The Center for Frontier Science and Engineering, University of Electro-Communications, Japan.
We successfully demonstrate, for the first time, error-free 320-Gb/s all-optical wavelength conversion using cross-gain modulation in a quantum-dot semiconductor optical amplifier. We further demonstrate full C-band operation at 160-Gb/s with low power penalties.

CHARACTERIZATION OF FWM-INDUCED CROSSTALK FOR WDM OPERATION OF A FIBER-OPTICAL PARAMETRIC AMPLIFIER
Robert Elschner1, Thomas Richter1, Colja Schubert1
1Fraunhofer Institut for Telecommunications/Heinrich Hertz Institute, Germany.
We show by simulations and experiments that WDM-interchannel crosstalk in fiber-optical parametric amplifiers can be characterized by an effective noise figure. This depends only on the ratio of pump power to total WDM-bands output power.

PHASE-ENCODED SIGNAL REGENERATION EXPLOITING PHASE SENSITIVE AMPLIFICATION
David Richardson1, Radan Slavik1, Joseph Kakande1, Francesca Parmigiani1, Adonis Bogris2,3, Dimitris Syvridis2, Periklis Petropoulos1
1University of Southampton, United Kingdom; 2National and Kapodistrian University of Athens, Greece; 3Department of Informatics, Technological Educational Institute of Athens, Greece.
We discuss recent advances in phase-sensitive amplification technology and review its application to the regeneration of multi-level phase-encoded signals.

ALL OPTICAL RECONFIGURABLE RADIO FREQUENCY UP/DOWN-CONVERSION USING OPTICAL PARAMETRIC LOOP MIRROR

1University of Southern California, USA.
A method of reconfigurable frequency up/down-conversion using an optical parametric loop mirror is proposed. Up-conversion of up to 60GHz and down-conversion from 40GHz for single and WDM signals are demonstrated.
 
Mo.1.A.5 • 15:45
DWDM-TO-OTDM CONVERSION BY TIME-DOMAIN OPTICAL FOURIER TRANSFORMATION
Hans Christian Hansen Mulvad1, Hao Hu1, Michael Galili1, Hua Ji1, Evarist Palushani1, Anders T. Clausen1, Leif K. Oxenlowe1, Palle Jeppesen1
1DTU Fotonik, Technical University of Denmark, Denmark.
We propose DWDM-OTDM conversion by time-domain optical Fourier transformation. Error-free conversion of a 16×10 Gbit/s 50 GHz-spacing DWDM data signal to a 160 Gbit/s OTDM signal with a 2.1 dB average penalty is demonstrated.
 
Mo.1.A.6 • 16:00
TRUE TIME DELAYS USING CONVERSION/DISPERSION WITH FLAT MAGNITUDE RESPONSE FOR WIDEBAND ANALOG RF SIGNALS
Omer F. Yilmaz1, Lior Yaron2, Salman Khaleghi1, Mohammad Chitgarha1, Moshe Tur2, Alan Willner1
1Electrical Engineering, University of Southern California, USA; 2School of Electrical Engineering, Tel Aviv University, Israel.
We demonstrate optical true time delays using wavelength conversion coupled with chromatic dispersion. Using offset pumps, < 1 dB magnitude response fluctuations over ~40 GHz of bandwidth is achieved. Calculated linear frequency-modulated impulse response maintains a <-32 dB peak-to-sidelobe-ratio.
