TL;DR: To the best of the authors' knowledge, this is the first 2 µm region NOLM-based mode-locked fiber laser operating at two regimes with the highest single pulse energy for NL pulses.

TL;DR: An all-fiber Tm(3+)-doped silica fiber laser operating at a wide selectable wavelength range is demonstrated by using different fiber Bragg gratings (FBGs) as wavelength selection elements.

TL;DR: The 81° tilted fiber grating (81°-TFG) based sensor has shown a lower thermal cross-talk effect, better linearity and higher Q-factor in sensing response, and can be further improved by increasing the grating length and/or choosing a higher-order cladding mode for detection.

TL;DR: In this article, a graphene oxide (GO) nanosheets functionalized long period grating (LPG) was used for ultrasound hemoglobin sensing, based on the measurement of LPG resonant intensity change induced by the adsorption of hemoglobin molecules onto GO, where GO as a bio-interface linkage provides the significant light-matter interaction between evanescent field and target molecules.

TL;DR: It is verified that one of the dual peaks at the shorter wavelength is due to the TM mode coupling whereas the other one at the longer wavelength arises from TE mode coupling when a linearly polarized light launched into the Ex-TFG.
