Photonic crystal bic
Although this spin model cannot be directly applied for electrons because of neglecting the orbital motion of electrons in the magnetic field, it has one-by-one correspondence to the polarized light reflection from an anisotropic defect layer (ADL). The aim of this paper is realization of the FW BICs in the … See more Due to the one-by-one correspondence between the spin of the electron and the polarization state of light (Table 1), we illustrate the one-dimensional FW BICs first in a toy quantum … See more For experimental verification, the model was modified to facilitate fabrication and measurement (Fig. 3a) where the right 1D PhC arm was replaced by a gold mirror film with refractive … See more WebApr 4, 2024 · In this letter, we propose a reflective photonic crystal (PhC) to generate vortex beam and demonstrate the superimposition of topological charges in the momentum space between PhC and the vortex beams. In addition to BICs, we demonstrate that other singularities like degenerate point can also be used to generate vortex beams.
