TL;DR: A comprehensive survey of photosensitivity in silica glasses and optical fiber is reviewed in this article, where the mechanisms contributing to germanium or aluminum doped fiber photosensitivity are discussed within the framework of photoelastic densification models.

TL;DR: In this paper, photo-induced Bragg reflectors at 1480 nm are written at both ends of the fiber amplifier and laser oscillation clamps the gain and suppresses low frequency signal or pump induced gain fluctuations.

TL;DR: In this article, the influence of ion-pair concentration on the dynamical behaviour of erbium-doped fiber lasers was demonstrated. But the authors focused on the effect of ion pair density on the output of the laser and showed that the output intensity evolves continuously from an infinite train of pulses to a CW steady state as the pumping ratio increases.

TL;DR: In this article, an optical multiplexer adds to a group of optical signals, whose wavelengths belong to a groups of wavelengths (λ 1... λN) and drop from said group of signals at least one optical signal having a given wavelength, chosen from within the wavelength group and comprising at least 1 optical circulator (C1, C2) having an input for receiving the group of signal and an output, an optical selection means (MS) coupled, on one side, to the circulator and which comprises at least a photoinduced Bragg grating

TL;DR: The generation of 30-W peak-power 250-fs-wide pedestal-free optical pulses at 1.54 microm by use of a chirpcompensated optically amplified semiconductor laser followed by simultaneous soliton compression and shaping within a nonlinear optical loop mirror is reported.
