(a) Schematic top view of the cell. Small arrows illustrate the director distribution in the absence of external perturbation (voltage and/or light). The large arrows represent the input wave vectors. (b) Sketch of propagation vectors ${\mathbf{k}}_j$ with respect to the optic axis $\widehat{n}$. Rotated reference frames $x{t}_1{s}_1$ and $x{t}_2{s}_2$ are indicated, as well.Reuse & Permissions

Figure 2

Acquired intensity profiles for red light in the plane $ts$ (i.e., after a rotation by $\delta$). Contour maps of the calculated intensity distributions are superimposed (white lines) to the experimental data. (a) A weak 0.1 mW red beam is colaunched with a 1.2 mW NIR beam; (b) a 0.4 mW red beam is injected in the absence of NIR; (c) 0.4 mW red and 1.2 mW NIR beams are colaunched and generate a vector soliton. In the simulations, we took effective input coupling efficiency of 40% and 50% for red and NIR and initial beam curvatures of radius $-130\mu \mathrm{m}$ (waist in $z=-40\mu \mathrm{m}$), respectively.Reuse & Permissions

Left: acquired intensities profiles at 632.8 nm in the plane $yz$. Intensity levels are normalized to scattering. Right: corresponding computed intensities in the plane $st$. Input power $P_{\mathrm{R}}$ at 632.8 nm is 1.6 mW, while NIR powers are $P_{\mathrm{NIR}}=0$ (a),(b), 0.7 (c),(d), and 2.4 mW (e),(f), respectively. Incoupling parameters are as in Fig. 2.Reuse & Permissions

Figure 4

Red peak intensity $I_R(s)$ in the observation plane $st$ (right axes) versus $s$ and total excitation $P_{\mathrm{R}}+P_{\mathrm{NIR}}$ (left axes) for a fixed $P_{\mathrm{R}}$. (a)–(d): measured data; (e)–(h): calculated data (after integration along $x$) assuming coupling parameters as in Fig. 2. $P_{\mathrm{R}}$ is 0.1 (a),(e), 0.4 (b),(f), 1.0 (c),(g), and 1.6 mW (d),(h), respectively. All data are normalized to the value in $s=0$.Reuse & Permissions
