Abstract The Finite Difference Time Domain (FDTD) method is used for the simulation, and a
new method based on critical coupling and guided resonance is proposed theoretically and …

Optical fibers have been widely applied to telecommunication, imaging, lasers, and sensing.
Among the different types of fibers, photonic crystal fibers (PCFs), also called …

A surface plasmon resonance (SPR) chemical sensor comprising microstructured optical
fiber (MOF) is designed for refractive index (RI) sensing in the visible to near-infrared (0.42 …

This paper proposes a dual-frequency tunable ideal visible light metamaterial absorber
based on the sub-wavelength range, which achieves perfect absorption in the visible light …

This paper propose a perfect absorber with multi-band, adjustable, high figure of merit
(FOM) and high sensitivity is based on single-layer patterned graphene surface plasmon …

In this paper, a multi-band multi-tunable graphene absorber structure is proposed. The
absorber is made by “+” intersecting double-ellipse graphene, L-shaped graphene layer …

This research presents a novel link between refractive index sensing and spectroscopy by
designing a “photonic crystal fiber” based “refractive index (RI)” sensor. The proposed …

Metamaterial absorbers have attracted more and more attention because they can achieve
perfect absorption in some specific structures. At present, although most absorbers can …

In this study, we propose a design and simulation of a highly sensitive surface plasmon
resonance (SPR) based single-mode D-shaped optical fiber refractive index sensor in the …

A high-sensitivity surface plasmon resonance (SPR) sensor is designed and analyzed
numerically. The sensor is constructed on the eightfold U-shaped photonic quasi-crystal …
