“…When the propagation constant of the HE1,1 mode is equal to that of the metal SPP mode, SPR is excited according to Eq. (2): 34 kHE1,1=ω0cεd sin θSP=kSP,where ω0 is the plasma frequency, c represents the speed of light in vacuum, ε0 represents the dielectric constant of the target medium, and θSP is the resonance angle. In addition, under resonance conditions, the energy exchange between the HE1,1 mode and SPP mode is the most intense and the confinement loss determined by Eq.…”

With the continuous development of optical fiber sensing technology, the photonic crystal fiber (PCF) sensor based on surface plasmon resonance (SPR) excited by the LP 0;1 mode has attracted extensive attention. In this work, an SPR PCF excited by the HE 1;1 mode is designed and the various structural parameters are optimized from the perspective of the wavelength sensitivity. The phase matching, mode field distribution, wavelength sensitivity, amplitude sensitivity, structural parameter sensitivity, and figure of merit (FOM) of the PCF-SPR sensor are systematically and comprehensively analyzed numerical by the finite element method and the characteristics are compared to those of representative PCF sensors reported in recent years. The highest wavelength sensitivity of the PCF-SPR sensor is 25;800 nm∕RIU, resolution is 3.87 × 10 −6 RIU, and FOM is 289.83 RIU −1 . The excellent sensing properties suggest that the sensor has immense potential in petroleum logging, geological exploration, and other applications.

A simple temperature sensor based on ZnO composite graphene is demonstrated. With the temperature changes, the electron mobility of ZnO composite graphene changes accordingly, which leads to an effective change in the refractive index of ZnO composite graphene. Experimental results show that micro-nano fiber coated with spherical ZnO composite graphene exhibits a higher sensitivity of 0.018 dB/°C in the temperature range of 25-60°C.Overall, the results verify the effectiveness of the proposed temperature sensor in accurate temperature measurement and offer a new, unique, and convenient direction for temperature sensing.

When two synchronized laser beams illuminate the inner surface of bulk lithium niobate crystals with magnesium doping (5%/mol MgO:LiNbO 3 ) under the condition of total reflection, semi-degenerate four-wave mixing (FWM) is generated. On this basis, a more sophisticated frequency conversion process on the interface of nonlinear crystal has been researched. The generation mechanism of FWM is associated with the fundamental waves reflected on the inner surface of the nonlinear crystal. Analysis of the phase-matching mechanism confirms that the FWM is radiated by the third-order nonlinear polarized waves, which are stimulated by the third-order nonlinear susceptibility coefficient of the nonlinear crystal. Theoretically calculated and experimentally measured corresponding data have been presented in this article. These results are expected to provide new inspiration for further experimental and theoretical research on frequency conversion in nonlinear crystals.
