One of many fiber nonlinear effects is a four-wave mixing (FWM) phenomenon that is resonant when the phase matching condition is satisfied. It only occurs for particular combinations of fiber dispersion and signal frequencies. In particular, phase matching is achieved for signals with very similar frequencies propagating near the zero dispersion wavelength(More)
We present a new Fast Frequency Selective Keyhole (FFSK) method, which allows dynamic acquisition of a low-resolution image signal from the arbitrarily chosen k-space points and reduces acquisition time of the conventional keyhole approach. Off-resonance components are eliminated by the filtering procedure which substantialy increase SNR. The effect of the(More)
