Conventionally, the polarization state of light is modulated by birefringence in crystals, which causes phase retardation for two orthogonally polarized wave components during light propagation. The corresponding optical components are usually bulky and suffer from several problems such as narrow operating ba...

transmission, in a manner preserving its polarization, of light of a linear polarization state using an optical fiber having a linear birefringence of an amount sufficient to provide extensive decoupling of the polarization-degenerate modes of oscillation of the light that can propagate within the ...
On the basis of a reversible nonlinear process leading to the self- organization of light SOP in optical fibres, here we show that a spying operation can be completed for an arbitrary time window or, alternatively, that the data can be continuously kept hidden. We analyse the performance of...
Because the probe light field is very weak, it is reasonable to believe that the atomic population remains in the initial state |1〉, which means a1 ≈ 1. Based on the steady-state solutions (\({\dot{a}}_{i}=0\), i = 1, …, 5) of the above Eqs (2)–(6), we ...
Over the past decades, studies on wave optics have been extended to the microscale and even nanoscale realm, yielding the new field of metaphotonics that enables unprecedented manipulations of light-matter interactions. Metaphotonics is a novel direction of research regarded as metamaterial-enabled photon...
such that the major axis of the elliptic jacket extends perpendicular to the substrate surface; abrading away the substrates together with the fiber embedded therein from the major surface to a depth where light traveling in the core of said fiber may leak out; placing one substrate on the othe...
In order to be applied to the estimation of the actual carrier rotation angle, the dynamic application research experiment is carried out. The center region is chosen as the true value of AOP. The error is about −0.7°∼+0.5°. It proves that the proposed algorithm is effective and ...
It provides a new understanding that controlling domain geometry can further enhance the light-emitting and photovoltaic performance of perovskite-based applications. The observation proves that the anisotropy of photoexcited transition dipoles is existed in the electronic states of MAPbBr3. Particularly, ...
High refractive index (RI) thin films are capable of pulling waveguide mode profiles towards themselves. In this study, it is shown that by applying high RI coatings with specific thicknesses on the side of optical waveguides, significantly different mod
