We show the existence of nonlinear resonant states in a higher-order Schrödinger model that appertains to wave propagation femtosecond fiber optics, under certain parametric regime. These are analytically illustrated terms Gaussian beams, Airy and periodic beams resulted due presence quadratic, linear, constant type ‘smart’ potentials, respectively, ensuing model. Interestingly, chirp associate...

Disturbances of the cardiac conduction system constitute a major risk after surgical repair of complex cases of congenital heart disease. Intraoperative identification of the conduction system may reduce the incidence of these disturbances. We previously developed an approach to identify cardiac tissue types using fiber-optics confocal microscopy and extracellular fluorophores. Here, we applied...

One of the factors which limits the transmission capacity of the fiber optics communication channel is the material dispersion. Exact analytical study of the material dispersion is often complex and involves calculating the derivatives of the refractive index of the core. These calculations are too cumbersome to do, especially for high-order derivatives. So material dispersion has only been stu...

In recent years, 3D printing glass optics has gained massive attention in industry and academia since could be an ideal material to make optical elements, including the lens. However, limitation of materials methods prevented progress. Therefore, we have developed a novel strategy for germanate instead pure silica. Moreover, compared with traditional multi-component quartz glass, unmatched adva...
