An Ag-graphene layers-coated H-shaped photonic crystal fiber (PCF) surface plasmon resonance (SPR) sensor with a U-shaped grooves open structure for refractive index (RI) sensing is proposed and numerically simulated by the finite element method (FEM). The designed could solve problems of air-holes material coating analyte filling in PCF. Two big x-axis produce birefringence phenomenon leading to confinement loss sensitivity x-polarized light being much stronger than y-polarized. Graphene...
Nowadays, detection of pesticide residues is generally conducted in the laboratory using large-scale equipment such as liquid chromatography mass spectrometry, etc. These methods usually require a complicated pre-treatments and professional operators, which are time-consuming expensive. Surface-enhanced Raman scattering (SERS) technology makes trace implementable, but currently devices for SERS on market all rapid has not been achieved yet. In this paper, novel system integrated with...
Due to their flexible structure and excellent optical characteristics hollow-core photonic crystal fibers (HC-PCFs) are used in many fields, such as active devices, communications, fiber sensing. In this paper, analyze the of HC-PCFs, we carried out finite element analysis analyzed design for band gap cladding HC-PCFs. First, HC19-1550 HC-1550-02 C-band were simulated. Subsequently, structural optimization seven-cell variations optimized wavelength range 1250–1850 nm investigated. The...
We propose a sensitivity enhanced surface plasmon resonance (SPR) sensor with two-dimensional (2D) hydrogen doped molybdenum oxide (HMO) nanodisks integrated onto an Au-coated optical fiber. Through ionic doping, the exhibits tunable plasmonic in visible to near-infrared wavelength region, which turn enhances light-matter interaction. A resonant peak redshift of fiber is observed due deposition HMO. Within certain thickness, refractive index (RI) has positive correlation ion doping...

In this paper, we propose a tunable terahertz metasurface Salisbury screen (MSS) based on graphene, which achieves adjustable broadband absorption through controlling the bias voltage applied graphene sheet. Combining conventional (CSS) with specially optimized metasurface, distributed resonances can be excited in continuous wide bandwidth. Meanwhile, material is introduced to replace ohmic sheet manipulate surface resistance. The simulated results show that graphene-based MSS has bandwidth...
To solve the problems of traditional integral imaging, such as poor visual quality, ray-crosstalk in display, and grainy obvious, a display method based on discrete glued lens array holographic diffuser is proposed.
