TL;DR: Using pulse trapping and amplification, the phenomenon of orthogonally polarized pulse trapping between a continuous-wave beam and an ultrashort soliton pulse in birefringent fibers is investigated both experimentally and numerically.

TL;DR: 3-D high-resolution spectral-domain optical coherence microscopy by using a supercontinuum (SC) fiber laser source with 300-nm spectral bandwidth with lateral and axial resolutions of 3.4 and 3.8 μm in tissue is presented, which is, to the best of the authors' knowledge, the highest 3-D spatial resolution reported among those of Fourier-domain Optical coherence imaging techniques in the 1700- nm spectral band.

TL;DR: In this paper, the authors demonstrated the control of optical pulse at visible region using pulse trapping by soliton pulse in photonic crystal fibers, where the wavelength of trapped pulse is continuously blue-shifted from 0.53 to 0.45 µm by changing the power of control pulse.

TL;DR: Although the axial resolution was reduced by a factor of ∼6 after passing through a 2-mm-thick tissue phantom, the result clearly showed that compensation of the dispersion mismatching allowed us to achieve an axialresolution of 4.3 μm in tissue and improve the SNR by ∼5 - dB compared with the case where dispersion mismatch was not compensated.

TL;DR: This work analyzed the amplification effect of orthogonally polarized pulse trapping in birefringent fibers both experimentally and numerically and clarified that this amplification effect is caused by stimulated Raman scattering between orthog onally polarized pulses.
