Novel method for measuring nonlinear coefficient in optical fibers based on phase mismatching four-wave-mixing is proposed. With simple setup, we demonstrate measurements for both high nonlinearity dispersion-shifted fiber and low nonlinearity standard SMF.
We experimentally demonstrate optical performance monitoring of 20-Gb/s return-to-zero differential quadrature phase-shift keying signals using an asynchronous delay-tap sampling technique. This method allows online monitoring of accumulated chromatic dispersion in the range from -600 to +600 ps/nm. We also show evaluation of optical signal-to-noise ratio at a level of 6.7 dB and monitor operation...
