TL;DR: The results show that the steepness of peak slope can be improved by increase of FBG reflectivities, and these kinds of filters can be used as narrow-band single-channel selectors and multi-channel wavelength de-multiplexing by properly choosing the length of cavities and reflectivities of FBGs.

TL;DR: In this article, the Mg content of Zn1-xMgxO film grown on A-sapphire substrates by plasma-assisted molecular beam epitaxy is measured by inductively coupled plasma (ICP) and electronic probe microanalysis (EPMA).

TL;DR: In this article, the authors proposed a new structure of broadband nearly-zero flattened dispersion highly nonlinear photonic crystal fiber (PCF) through optimizing the diameters of the first two inner rings of air-holes and the GeO2 doping concentration of the core, the nonlinear coefficient is up to 47 W-1 km-1 at the wavelength of 1.55 µm.

TL;DR: In this article, a novel solution for polarization mode dispersion compensation is proposed by applying tension on a tapered high-birefringence linearly chirped fiber Bragg grating.

TL;DR: In this paper, the authors theoretically investigate and optimize a multi-stage L-band EDFA including high-loss inter-stage element based on a reliable numerical model, and the results show that a piece of unpumped Erbium doped fiber should be placed before (forward pumping) or after (backward pumping) the loss element to improve the pump efficiency through ASE re-absorption, and by optimizing the EDF length of each stage properly, both high-output gain and uniform NF profile can be derived even with highloss interstage devices.
