Numerical investigation of optical properties in carbon tetrachloride-filled photonic crystal fibers
In this work, we design circular lattice photonic crystal fibers using Lumerical Mode Solution software, its hollow core filled with carbon tetrachloride. Optical properties including effective refractive index, chromatic dispersion, nonlinearity, and fiber loss were investigated numerically in detail based on solving Maxwell's wave equations.

In this paper, we show that there is a certain interval of input intensity, in which the transmission coefficients overlap one to other. This behaviors of SNC can be used to generate random signals. Using the expression described the output-input power relation, the expression of the optical merge signal, carrier signal and coded-carrier signal, the overlapping region of the input intensity is numerically observed.

Ebook "Metal-organic frameworks for photonics applications" is to give the reader, whether at a university or in industry, a comprehensive overview of an area where new insights are emerging that are of interest to a larger scientific audience. Thus each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years should be presented using selected examples to illustrate the principles discussed.

This energy difference can be an indicator of a compound’s excitability; the more readily a compound can be excited, the narrower the energy gap. The energy gap might be significantly affected by the influence of thermal energy. The non-linear optical (NLO) efficiency of methyl orange-doped (MOD) TBC crystals was contrasted with that of the pure form, and the doped version exhibited greater efficiency, particularly for high-frequency applications.
