Multiwavelength Brillouin-Erbium Random Fiber Laser Incorporating a Chirped Fiber Bragg Grating

Abstract: We experimentally demonstrate a multiwavelength Brillouin-erbium random fiber laser with a linear half-open cavity, by combining Rayleigh scattering with the reflection of a chirped fiber Bragg grating. The linear half-open cavity configuration is successful in obtaining multiwavelength random fiber laser with flattened output spectra, which is verified by both about 4.3 dB peak power difference between the first and fourth channel and inconspicuous peak power discrepancy between the odd and even Stokes lines. Up to five output channels with a spacing of about 0.088 nm, a linewidth of about 0.02 nm and optical signal-to-noise ratio over 15 dB have been obtained.

Hydrogen Generation from Water Splitting on TiO2 Nanotube‐Array‐Based Photocatalysts

Abstract: H2 production from water splitting by a photocatalytic process is one route that can be used to solve global issues related to energy depletion and environmental pollution, and it has attracted a great amount of attention in both the academic and industrial fields. TiO2 nanotube arrays are intensively investigated as TiO2 catalysts. In comparison to a TiO2 powder catalyst, the nanotube arrays have specific advantages, including a large surface area, easy retrievability, uniformly ordered structure, and size-dependent properties, all of which make them attractive in wide applications including H2 generation. In recent years, a large amount of work has been done and great progress has been achieved in this field. In this review, we summarize synthetic strategies to prepare TiO2 nanotube arrays and their modification methods, and we highlight recent progress in the generation of H2 on TiO2 nanotube-array-based materials. Finally, challenges associated with industrial application of this photocatalytic technique are also emphasized.
