We demonstrate both theoretically and experimentally nonparaxial Mathieu Weber accelerating beams, generalizing the concept of previously found beams. show that such beams bend into large angles along circular, elliptical, or parabolic trajectories but still retain nondiffracting self-healing capabilities. The circular can be considered as a special case while an Airy beam is only at paraxial limit. Not do generalized open up many possibilities engineering for applications, fundamental...
We report the experimental generation and dynamic trajectory control of plasmonic Airy beams (PABs). The PABs are created by directly coupling free-space to surface plasmon polaritons through a grating coupler on metal surface. show that ballistic motion can be reconfigured in real time either computer addressed spatial light modulator or mechanical means.
We study linear and nonlinear self-accelerating beams propagating along circular trajectories beyond the paraxial approximation. Such nonparaxial accelerating are exact solutions of Helmholtz equation, preserving their shapes during propagation even under nonlinearity. generate experimentally observe directly these large-angle bending in colloidal suspensions polystyrene nanoparticles.
A compact high temperature sensor utilizing a multipath Michelson interferometer (MI) structure based on weak coupling multicore fiber (MCF) is proposed and experimentally demonstrated. The device fabricated by program-controlled tapering the spliced region between single mode (SMF) segment of MCF. After that, spherical reflective formed arc-fusion splicing end face Theoretical analysis has been implemented for this specific MI structure; beam propagation method simulation corresponding...
An approach to rationally tune the optoelectronic properties of dithienobenzodithiophene derivatives (DTBDTs) and DTBDTs-based conjugated polymers has been demonstrated.
Utilizing the periodicity of rotating machinery, dynamic clearance measurement can be achieved with a single swept light source without any additional auxiliary devices, which has advantages simplicity and reliability. However, there is shortcoming that previous algorithm not fast enough to achieve real-time when machinery rotates at high speed. Aiming this shortcoming, utilizing correlation between mimic signal signal, combined information for multiple periods, algorithms corrected model...
2-μm fiber lasers are of wide potential applications in the fields radar, sensing, and free-space communications. We introduced a simple approach to generate passively mode-locked pulse thulium-doped based on nonlinear polarization rotation (NPR) our previous work. The high repetition rate 1.78 GHz is obtained by both NPR semiconductor saturable absorption mirror. By using polarization-maintaining experiment, birefringence Lyot filter as comb can be constructed, then tuning range 94 nm for...
Aiming at the problems of Doppler-induced error and slow measurement rate in frequency-swept interferometry, a novel dynamic clearance measuring method is proposed. By combining frequency-fixed using fusion processing interferometric signals, this not only can eliminate error, but also give value each sampling point. To verify method, an all fiber-optic system was constructed, experiments under 500 Hz triangular 4 kHz sinusoidal vibrations were carried out. Experimental results show that be...
We propose a novel approach to visualize the light-induced refractive index changes in photorefractive crystals employing digital holography. The holograms formed Mach-Zehnder interferometer are recorded by two-dimensional CCD camera. From these holograms, phase differences, which contain information of crystals, determined utilizing holographic interferometry. Then visualizations can be obtained. This method is successfully demonstrated LiNbO3:Fe, KNSBN:Ce and SBN:Cr crystals.
An energy‐preserving scheme is proposed for the three‐coupled nonlinear Schrödinger (T‐CNLS) equation. The T‐CNLS equation rewritten into classical Hamiltonian form. Then spatial variable discretized by using high‐order compact method to convert it a finite‐dimensional system. Next, second‐order averaged vector field (AVF) employed in time which results an scheme. Some theoretical such as convergence are investigated. In addition, provides some numerical examples illustrate robustness and...
