This research investigates the visible upconversion luminescence which is induced by multiphoton absorption of soft glass fiber defects. The study of this phenomenon has thus far been restricted to standard silica fibers. We observed the emission of

We report the experimental demonstration of efficient second-harmonic generation by splicing optically poled fiber segments. A device made from five segments each 20 cm-long exhibits, at a fundamental average power of 4.2 mW, a maximum increase of 5.

Optical poling is a very simple technique for inducing a quadratic nonlinearity in germanium-doped silica fibers [1] , [2] . By injecting into the fiber fundamental frequency (FF) pulses together with a low power second harmonic (SH) seed, a multi-ph

We experimentally demonstrate dual-polarization nonlinear frequency division multiplexing using the continuous spectrum in 1680 km of normal dispersion fiber at a burst rate of 128Gbit/s. The DGD penalties are shown to be negligible.

We experimentally demonstrate dual-polarization nonlinear frequency division multiplexing (NFDM) using the continuous spectrum in 1680 km of normal dispersion fiber, at the net data rate of 25.6 Gb/s. NFDM exhibits a gain of 0.4 dB in $Q$ -factor and

Nonlinear frequency-division multiplexing is compared with OFDM in experiment. NFDM exhibits a peak Q-factor gain of 0.7 dB (1 dB in SNR) over OFDM, in an experiment using normal dispersion fiber with 16QAM modulation, 16 Gbd, 32 sub-carriers and 140
