Low Threshold, Wide Dynamic Range, Tunable, All-Optical Self-Modulator Based on Fano Resonance and Out-of-Plane Coupling in a Slab Photonic Crystal with a Graphene Layer

<div>Schematic of the THz modulator. It consists of a one-dimensional (1D) slab PhC and a layer of graphene (Gr). A continuous infrared wave with a wavelength of 1550 nm is inputted from upside and self-modulated after transmission from the structure.</div>
