The technological evolution has been progressing for centuries and will possibly increase at a higher rate in the 21st century.
Since the last decades, non-precious metal catalysts (NPMC), especially iron based electrocatalysts show sufficient activity, potentially applicant in oxygen reduction reaction (ORR), however they only withstand considerable current densities at low operating potentials. On other hand are not stable elevated cathode potentials, which is essential for high energy competence, and its remains difficult to deal. Therefore, via this research a simple approach demonstrated that allows synthesis of...
Depolarizing behavior is commonly observed in most natural samples. For this reason, optical tools measuring the differences depolarization response among spatially separated structures are highly useful a wide range of imaging applications for enhanced visualization structures, target identification, etc. One used tool depolarizing discrimination so-called spaces. In article, we exploit combined use two spaces, indices polarization purity (IPP) and polarizance–reflection–transformation...
Vertically aligned silicon nanowires (SiNWs) were cost-effectively formed on a four-inch wafer using simple room temperature approach, i.e., metal-assisted electroless etching. Tapering the NWs by post-KOH dipping achieved separation of each NW from bunched NW, resulting in strong enhancement broadband optical absorption. As etching time increases, crossover feature was observed tradeoff between enhanced light trapping (by graded-refractive index during initial tapering) and deteriorated...
In the free space optical communication, information can be encoded as orbital angular momentum (OAM) state of light, which is called OAM shift keying (OAM-SK). This paper has proposed a communication system with OAM-SK, in an image been delivered from transmitter to receiver successfully simulation environment. Specifically, we have carefully designed and implemented phase holograms used at for multiplexing de-multiplexing states, respectively. At transmitter, hologram by modified Lin's...
A broadband metamaterial lens that does not suffer from chromatic aberration is of particular interest for optical applications at midinfrared frequencies. Due to the intrinsic dispersion building blocks, though, such a achromatic metalens has remained elusive. The authors use Pancharatnam-Berry phase and propagation control wave front light, which can be eliminated effectively. This result points way practical devices, $e.g.$ communication technology.
The vortex beam carrying orbital angular momentum (OAM) has attracted great attentions in optical communication field, which can extend the channel capacity of system due to orthogonality between different OAM modes. Generally, atmospheric turbulence distort helical phase fronts beams, presents a critical challenge effective recognition Recently, convolutional neural network (CNN), as model deep learning, been widely applied machine vision. In this paper, based on CNN theory, we make...
Abstract MXene is a promising two-dimensional (2D) material that widely used in electro-photonic devices due to its unique properties. In this contribution, V 2 CT x , novel MXene, was employed as saturable absorber (SA) for hybrid passively mode-locked fiber lasers. An ultra-stable and self-starting laser system with low threshold can be achieved using nanosheets nonlinear polarization evolution (NPE). Signal noise ratio increased 13 dB compared only NPE SA. A 72 fs pulse duration easily...
Thermal radiation control has attracted increasing attention in a wide range of field, including infrared detection, radiative cooling, thermal management, and camouflage. Previously reported emitters for camouflage presented disadvantages lacking either tunability or stability. In this paper, we propose tunable emitter consisting metal-insulator-metal (MIM) plasmonic metamaterial based on phase-change material Ge2Sb2Te5 (GST) to realize wavelength ranges from 3 μm 14 μm. Meanwhile, the...
Visible-infrared compatible camouflage is important to increase the counter-detection ability of a target due fast development detection systems. However, most previously reported visible-infrared structures are not suitable when temperature targets and type background environment change. In this paper, we propose tunable infrared emitter composed ZnS/Ge/Ag/Ge2Sb2Te5/Ag films numerically demonstrate radiation heat dissipation. Firstly, proposed can produce different structural colors as...
Dynamically manipulating the spectra and polarization properties of thermal radiation is key to counter an infrared imaging system (IPIS) under different background environments. In this Letter, we propose a phase-change metasurface emitter (PCMTE) composed vanadium dioxide (VO 2 ) dipole antenna arrays dynamically manipulate polarized in long-wave (LWIR) region 8–14 µm. During thermally induced reversible insulator-to-metal transition (IMT) VO , by simulating LWIR images at angles for PCMTE...
Silicon nanowires (NWs) and microwires (MWs) are cost-effectively integrated on a 4-inch wafer using metal-assisted electroless etching for solar cell applications. MWs periodically positioned low-level optical patterning in between dense array of NWs. A spin-on-doping technique is found to be effective the formation heavily doped, thin n-type shells which radial doping profile easily delineated by low voltage scanning electron microscopy. Controlled tapering NWs results additional...
