The hierarchical porous thin films have a very low refractive index, 1.14 at 633 nm, lower than the 1.17 value measured for the monomodal mesoporous films. The introduction of templating nanoparticles ...

In this paper, a pure silica core photonic crystal fiber with multi-coating layers (Au and Tantalum pent-oxide) for high refractive index (RI) sensing is proposed, which can offer higher accuracy of ...

Abstract: We propose a surface plasmon resonance (SPR) refractive index (RI) sensor based on an active Yb 3+-doped photonic crystal fiber (PCF) in this paper. With the proposed sensor, using the pump ...

Nonlinear refractive index of Au nanoparticle suspended in PVA solution was measured using a single beam Z-scan technique. Measurements were carried out using a green CW laser beam operated at 532 nm ...

A new economic and social impact report from Grant Thornton has claimed that Infracapital-backed network operator Fibrus, which is building a full fibre (FTTP) broadband ISP network across several ...
