Design and Characteristic Study of Terahertz Photonic Crystal Fiber for Orbital Angular Momentum Modes

In this paper, we design a new type of terahertz orbital angular momentum (OAM) optical fiber with excellent transmission characteristics over a wide frequency range. Within the 0.8–1.8 THz frequency band, it shows stable support for transmission of the fifth-order OAM mode. Its dispersion control e...
