Vitreous systems based on antimony oxide Sb$_{mathbf {2}} mathbf {O} _{mathbf {3}}$ have been investigated. The limits for glass formation are reported in the Sb$_{mathbf {2}} mathbf {O} _{mathbf {3}}$-PbO-ZnO ternary system. Thermal measurements implemented by differential scanning calorimetry show that Tg is above 300°C. As a general trend, Tg increases with zinc oxide content. The influence of the ZnO substitution on the optical and physical properties has been studied in the (80$-textbf{x}$)Sb2O3-20PbO-xZnO system: Vickers micro-hardness, Young’s modulus increase as zinc oxide concentration increases. An inverse dependence is observed for density. U.V. transmission stabilized around 75% and extended IR transmission is obtained. This behavior is discussed in relation to structural hypothesis.

Dual-wavelength operation of Yb:YAP laser with an intracavity birefringent filter (BRF) was demonstrated. By using a 1 mm-thick BRF, DW pairs with wavelength separation ranging from 1.8 nm up to 11.3 nm could be generated based on gain balancing provided by a single transmission peak of the filter. In this way, the wavelength separation was not limited by the available free spectral range of the filter.

We present an optimization study for the magic carpet parameters. Using simple models and scalar diffraction theory, we calculate the light sheet depth of field (DOF) and thickness for different mask dimensions. Experimental results confirm the numerical results. The results serve as a guideline for selection of the mask depending on the application.

A laser-based power and data delivery scheme is described for completely wireless operation of a epiretinal prostheses. Laser steering is achieved using a single, two-axis microelectromechanical system mirror and a custom curved reflection optic are used to enable beam trajectories at different angular coordinates of the pupil. Real-time pupil detection and laser steering operation are characterized on a 3D printed robotic eye platform and optimized for maximum optical power delivery.

We study the propagation of intense multi-frequency optical beams under the effect of Kerr nonlinearity. Soliton solutions with mixed topological charges were obtained numerically for certain frequency ratios in both resonant and non-resonant regimes. These findings lead to a better understanding of critical power for self-similar multi-color collapse and could lead to novel types of filament propagation.

Here, we propose to design a new class of glass/metal composite fibers for all-guided optical-electrical signals. The objective is to combine metal and glass materials by using additive manufacturing approach to engineer multimaterials fibers. Thus, after manual insertion of metallic electrodes into the tellurite glass preform, we can obtain the first tellurite-based core-clad dualelectrode composite fiber made by direct, homothetic preform-to-fiber thermal co-drawing.

We present a novel design of a metamaterial perfect absorber (MPA) operating at mid-infrared (MIR) and near-infrared (NIR) regimes. The proposed MPA is formed by a crossed ellipse in the center of a thick circular ring with both made of silver. A dielectric layer is sandwiched between this metallic structure and a silver ground plan. The geometrical dimensions are carefully optimized such that two absorption bands at $2.7~mu text{m}$ and $6~mu text{m}$, whose peaks are over 99%, are created. The horizontally and vertically symmetric design allows polarization-free operation. The proposed concept offers a tunable design for detection, imaging, energy harvesting, and stealth applications.
