Advanced Optical Materials, EarlyView.New fluorescent optical antennas are realized and tested for diverse Optical Wireless Communication (OWC) applications. The fluorescent concentrator slabs, based on different organic fluorophores, convert and convey the digital data conveyed through intensity modulation of incoming light toward a small‐area photodiode.

Advanced Optical Materials, EarlyView.Light impinging from the left on a metasurface composed by active material. The metasurface shows asymmetric configuration through the non‐uniform presence of holes. The forming quasi‐BICs modes are exploited for lasing purposes. Abstract It is proposed and numerically demonstrated a novel strategy to achieve lasing generation from a dual‐band symmetry‐

Multiservice Telecommunication Systems Parametrical Synthesis by using of Multilayer Graph Mathematical Model [PDF]
arXiv, 2012 This study is devoted to the problem of parametric synthesis of multi-service telecommunication sys-tems. The main characteristics of telecommunication systems, which are brought to account in an article, are multilayer structure formed by the overlayed networks and presence flows with self-similarity effect.

High Fidelity Waveguides Through Vitreous Media Recomposition for Next Generation Photonic Devices
Advanced Optical Materials, EarlyView.A newly designed aluminosilicate glass enables the fabrication of femtosecond laser‐written optical waveguides with ultra‐low propagation losses of −0.020 dB cm−1 at 1310 nm and −0.037 dB cm−1 at 1550 nm. Raman, Brillouin, and electron microscopy analyses reveal the mechanisms behind refractive index modifications, highlighting the role of glass ...
