A comprehensive analysis of a hydrothermally prepared Au nanoparticle decorated nanocomposite of reduced graphene oxide (rGO) and a ZnO nanorod (NR) for possible use as a UV photodetector is presented. The effect of rGO loading in ZnO and incorporation of Au decoration in the best combination of rGO/ZnO for possible enhancement of a photocatalytic effect are experimented. X-ray diffraction, scanning electron microscopy, energy diffraction, and UV-Vis spectroscopy are done for morphological, structural, and optical attribute analysis of the prepared materials. An increase in photocurrent is seen from 2.19 nA to 6.14 mA in dark and UV environments (370 nm) at 5 V bias voltage for the Au decorated nanocomposite, which is found to be better among the experimented composites. The responsivity and detectivity of the Au decorated nanocomposite are analyzed with the increase in incident UV light intensities. The findings are analyzed, and an explanation of the detailed UV photodetection mechanism is outlined in this paper.

We quantize the electromagnetic field in the presence of a nonmoving dielectric sphere in vacuum. The sphere is assumed to be lossless, dispersionless, isotropic, and homogeneous. The quantization is performed using normalized eigenmodes as well as plane-wave modes. We specify two useful alternative bases of normalized eigenmodes: spherical eigenmodes and scattering eigenmodes. A canonical transformation between plane-wave modes and normalized eigenmodes is derived. This formalism is employed to study the scattering of a single photon, coherent squeezed light, and two-photon states off a dielectric sphere. In the latter case, we calculate the second-order correlation function of the scattered field, thereby unveiling the angular distribution of the Hong–Ou–Mandel interference for a dielectric sphere acting as a three-dimensional beam splitter. Our results are analytically derived for a dielectric sphere of arbitrary refractive index and size with a particular emphasis on the small-particle limit. As shown in Phys. Rev. A 108 , 033714 ( 2023 ) PLRAAN 1050-2947 10.1103/PhysRevA.108.033714 , this work sets the theoretical foundation for describing the quantum interaction between light and the motional, rotational, and vibrational degrees of freedom of a dielectric sphere.

We study and design an ultra-broadband absorber based on TiN metamaterial. The proposed structure consists of a rectangle pillar, two rectangle rings, an Al 2 O 3 substrate, and a TiN substrate. The average absorption in the range of 300–4962 nm is 97.02%. The physical mechanism is illustrated by electric-field and magnetic-field distributions, including the dielectric lossy property of TiN itself in shorter wavelengths, Fabry–Perot resonance, and local surface plasmon resonance in longer wavelengths. The result indicates that the energy absorption spectrum can be well matched with the standard solar spectrum under AM 1.5 over the full range of 300–5000 nm, and then we compare the solar absorption spectrum of different structures. In the end, the influence of different materials and geometrical parameters on absorption is investigated. The absorber can achieve ultra-broadband perfect absorption, and has a simple structure that is easy to manufacture. The result of this work can be applied in many potential fields, for example, thermal photovoltaic power generation, infrared imaging, solar cells, and other optoelectronic devices.

We present a hill-shaped refractive index (HS-RI) structure in 16-core fiber that can provide 160 channels for the transmission system. The HS-RI mainly settles the issue of the large inter-mode crosstalk (IMXT) between LP 21 mode and LP 02 mode. We obtain the optimized parameters using the finite element method. Numerical analyses reveal that the inter-core crosstalk (ICXT) of all modes is smaller than −30dB/100km in the C band, and the effective mode refractive index difference (Δ n eff ) is more than 1×10 −3 . The minimum effective mode field area can achieve 89.80µm 2 , which greatly reduces the nonlinearity of fiber. The max dispersion is 15.59ps/(nm∗km), which can greatly guarantee signal quality in the transmission process. he relative core multiplexing factor (RCMF) can reach 65.81, which realizes the high space division multiplexing rate. The proposed fiber can be applied to a space division multiplexing system to enhance the fiber transmission channels and capacity.
提出了一种在16芯光纤中可提供160个传输通道的山丘形折射率(HS-RI)结构。HS-RI主要解决了lp21模式和lp02模式之间的大模间串扰问题。利用有限元法得到了优化参数。数值分析表明，C波段各模式的芯间串扰(ICXT)小于−30dB/100km，有效模式折射率差(Δ n eff)大于1×10−3。最小有效模场面积可达89.80µm 2，大大降低了光纤的非线性。最大色散为15.59ps/(nm * km)，在传输过程中极大地保证了信号质量。相对核心复用系数(RCMF)可达65.81，实现了高空分复用率。该光纤可应用于空分复用系统，以增强光纤传输通道和容量。
