TL;DR: In this paper, a small alteration that makes use of both the (M-1)th and conjugated (M + 1)th phase harmonics may reduce the undesirable gain variation.

TL;DR: In this article, the benefits of using a multi-segmented arrangement of optical fibers for self-phase modulation-based 2R optical regeneration are demonstrated both theoretically and experimentally.

TL;DR: This work characterize the spectral broadening performance in silica clad and unclad Tantalum pentoxide (Ta2O5) waveguides as a function of the input pulse central wavelength and polarization, and achieves octave spanning supercontinuum with an average power of 175 mW incident on the waveguide at 1000 nm pump wavelength.

TL;DR: In this article, the authors demonstrate all-optical regeneration of four WDM channels in a single optical fiber by using polarization multiplexing in a bidirectional configuration, and observe no performance degradation arising from the presence of the multiple channels.

TL;DR: In this paper, the phase of the spatial index modulation of fiber Bragg gratings is directly related to the temporal phase of its pulse response, and a pulse response method is proposed to directly characterize the phase, including the dc refractive index distribution (distributed phase shift), discrete phase, and chirp of fiber gratings (FBGs).
