| الوصف: | International audience ; Circularly polarized (CP) light is attracting growing interest in photonics, however it is not possible to use regular planar waveguides for the transmission of such CP light. While keeping the planar geometry, we conceived devices where the chirality of the propagation medium overcomes the planar symmetry. Thus, we report on the fabrication of chirowaveguides arising from the stacking of three layers of a new hybrid chiral organic modified silica (OrMoSil). A flexible strategy allows the control of the two main parameters impacting the ellipticity of the propagated waves. First, the high chirality of the transparent material is based on cheap and easy to access binaphthyl precursors simply shaped as films by dip-coating. Second, the refractive index (RI) contrast between the layers is finely tuned by TriEthOxySilane (TEOS) doping. The polarization of the two fundamental guided modes is measured on 2 cm long waveguides. We demonstrated that the polarization can be modulated from linear to nearly circular (80% ellipticity) depending on the RI contrast and the core thickness. These unprecedented achievements in the area of both optical materials and guided optics, open the way to fully integrated photonic devices dealing with CP light propagation. |
