Journal ArticleDOI
Fiber-optical analogue of the event horizon
TL;DR: This work used ultrashort pulses in microstructured optical fibers to demonstrate the formation of an artificial event horizon in optics and observed a classical optical effect: the blue-shifting of light at a white-hole horizon.
Journal ArticleDOI
Generation of Continuous Variable Einstein-Podolsky-Rosen Entanglement via the Kerr Nonlinearity in an Optical Fiber
Christine Silberhorn,Ping Koy Lam,Ping Koy Lam,O Weiss,F. Konig,Natalia Korolkova,Gerd Leuchs +6 more
TL;DR: The generation of a continuous variable Einstein-Podolsky-Rosen (EPR) entanglement using an optical fiber interferometer using the Kerr nonlinearity in the fiber to verify the nonseparability of the state.
Journal ArticleDOI
Negative frequency resonant radiation
E. Rubino,Joanna McLenaghan,S. C. Kehr,Francesco Belgiorno,David Townsend,S. Rohr,Christopher E. Kuklewicz,Ulf Leonhardt,F. Konig,Daniele Faccio +9 more
TL;DR: Measurements in both bulk media and photonic crystal fibres confirm predictions thatoliton resonant radiation emission leads to a second mode that originates from the negative frequency branch of the dispersion relation.
Journal ArticleDOI
Photon-Number Squeezed Solitons from an Asymmetric Fiber-Optic Sagnac Interferometer
TL;DR: In this paper, the authors demonstrated direct photon number squeezing in a nonlinear fiber-optic interferometer, where 126-fs solitons were launched into a highly asymmetric Sagnac loop.
Journal ArticleDOI
Extended phase matching of second-harmonic generation in periodically poled KTiOPO4 with zero group-velocity mismatch
F. Konig,Franco N. C. Wong +1 more
TL;DR: In this paper, the authors present extensive three-wave mixing measurements of the wave-vector mismatch and obtain improved Sellmeier equations for KTiOPO 4, and demonstrate a type-II extended phase-matching bandwidth of 100 nm for second-harmonic generation in periodically poled KTIOPO4, centered at the fundamental wavelength of 1584 nm.
