[CTuP3D-03] Alignment-Insensitive THz-OAM Wave Generator Based on Square Lattice Photonic Crystal
[Presentation Style] Onsite
For orbital angular momentum (OAM) wave generation, high-accuracy beam alignment is usually required. A photonic crystal (PhC)-based OAM wave generator is proposed and analyzed numerically. Very small alignment-dependence can be achieved with high efficiency.
