Th.11.LeCervin • Optical Amplifiers

Chair: David DiGiovanni; OFS, United States
 
Th.11.LeCervin.1 • 09:00 (Invited)
PHASE SENSITIVE FIBER OPTIC PARAMETRIC AMPLIFIERS
Peter Andrekson1; 1Chalmers University of Technology, Fotonik, Sweden.
A review of recent progress in nonlinear fiber-based phase-sensitive parametric amplifiers is provided. In addition, their use as in-line amplifiers, resulting in significant link performance improvement potential, is discussed.

TWO CHANNEL PHASE REGENERATION BASED ON A “BLACK-BOX” PHASE SENSITIVE AMPLIFIER
Paola Frascella1, Stylianos Sygletos1, Selwan K. Ibrahim1, Lars Grüner-Nielsen2, Richard Phelan3, James O'Gorman3,4, Andrew Ellis1; 1Photonic Systems Group, Tyndall National Institute, Ireland; 2OFS, Denmark; 3Eblana Photonics, Trinity College Enterprise Centre, Ireland; 4Xylophone Optics Ltd. 28, Ireland.
For the first time we demonstrate a “black-box” phase sensitive amplifier able to provide simultaneous suppression of phase distortion on two independent 42.66 Gbit/s DPSK modulated signal wavelengths.

PHASE SENSITIVE AMPLIFICATION IN A HIGHLY NONLINEAR LEAD-SILICATE FIBRE
Mohamed A. Ettabib1, Liam Jones1, Joseph Kakande1, Radan Slavik1, Francesca Parmigiani1, Xian Feng1, Francesco Poletti1, Giorgio M. Ponzo1, Jindan Shi1, Marco N. Petrovich1, Periklis Petropoulos1, Wei H. Loh1, David Richardson1; 1Optoelectronics Research Centre (ORC), University of Southampton, United Kingdom.
We experimentally demonstrate phase-sensitive amplification in a highly nonlinear lead-silicate W-type fibre. A phase-sensitive gain swing of 6dB was observed in a 1.56m sample of the fibre for a total launched power of 33dBm.
 
Th.11.LeCervin.4 • 10:00
PHASE AND AMPLITUDE TRANSFER FUNCTIONS OF A SATURATED PHASE-SENSITIVE PARAMETRIC AMPLIFIER
Carl Lundström1, Bill Corcoran1, Zhi Tong1, Magnus Karlsson1, Peter Andrekson1; 1Photonics Lab., Dept. of Microtechnology and Nanoscience, Chalmers University of Technology, Sweden.
We experimentally investigate the phase and amplitude transfer functions of a nondegenerate idler PSA in saturation. A regime in which phase noise can be reduced with very low amplitude penalty is identified.
 
Th.11.LeCervin.5 • 10:15
FIBER OPTICAL PARAMETRIC AMPLIFICATION OF OPTICAL COMBS FOR ENHANCED PERFORMANCE AND FUNCTIONALITY
Joseph Kakande1, Periklis Petropoulos1, David Richardson1; 1Optoelectronics Research Centre, University of Southampton, United Kingdom.
We demonstrate the inherent suitability of fiber optical parametric amplifiers (FOPAs) to the amplification of optical combs, combining gain, spectral shaping, frequency translation, effective spectral broadening and low noise amplification.
 
Th.11.LeCervin.6 • 10:30
AN ERBIUM-DOPED FIBRE AMPLIFIER WITH WIDELY VARIABLE GAIN EMPLOYING INTEGRATED COMPONENTS ON A PLANAR LIGHTWAVE CIRCUIT
Hirotaka Ono1, Toshio Watanabe1, Kenya Suzuki1, Atsushi Mori1, Tetsuo Takahashi1, Tadashi Sakamoto1; 1NTT Photonics Laboratories, NTT Corporation, Japan.
A 24 dB gain-range variable gain erbium-doped fibre amplifier with a 1.2 dB noise figure variation is demonstrated employing thermo-optic switches, variable optical attenuators, and pump/signal multiplexers integrated on a single planar lightwave circuit.
