Three-Dimensional Modeling of the Optical Switch Based on Guided-Mode Resonances in Photonic Crystals

Abstract: Optical switching is an essential part of photonic integrated circuits and the focus of research at the moment. In this research, an optical switch design working on the phenomenon of guided-mode resonances in a 3D photonic-crystal-based structure is reported. The optical-switching mechanism is studied in a dielectric slab-waveguide-based structure operating in the near-infrared range in a telecom window of 1.55 µm. The mechanism is investigated via the interference of two signals, i.e., the data signal and th… Show more

“…This unique application is due to the resonant coupling between the incident light and waveguide modes in the grating structure, creating devices capable of highly sensitive and selective detection. Because of this unique feature, GMR devices are made suitable for a variety of applications, including biosensing [1][2][3][4][5], optical filtering [6][7][8][9], and photonic technology [10].…”
