Fig. 18From: Optical vortices in waveguides with discrete and continuous rotational symmetryThe streamlines of the transverse component of the Poynting vector (grey lines) and the lines of zero intensity \({\vec {P_{t}}= (P_{x} = 0 (red lines) ; P_{y} = 0 (green lines))}\) for all solid band gap fiber with a cross section shown in Fig. 17 at a wavelength of λ=1μm.Back to article page
