In this article, the numerical simulations and experimental investigations on evolution of soliton rain in Tm-doped fiber laser were carried out, based nonlinear polarization rotation (NPR) technique. By carefully adjusting controller (PC) cavity, phenomenon was observed, which pulse train length a drifting solitons about 0.36 μs, 0.77 0.92 respectively. order to further analyze influence PC formation rain, corresponding analysis performed. The simulation consistent with results. Our present...
Abstract We present a graphene-based hybrid metasurface with quasi-bound states in the continuum (BICs) for manipulating terahertz (THz) wave absorption. By strategic application of structural perturbations THz metasurface, symmetry-protected BICs transforms into quasi-BICs. The incorporation graphene adeptly satisfies critical coupling condition, thereby facilitating attainment theoretical maximum absorption 0.5 quasi-BICs region. And Q-factor quasi-BIC can be up to 2755. Moreover, exhibits...
Abstract This study evaluated the applicability of TM doped CdS monolayers (TM-CdS, TM=Fe, Co, Ni, Cu) as sensing materials for detecting common harmful gases in mining environments. Using density functional theory, we conducted an in-depth on effect doping and simulated adsorption behavior CO NO molecules TM-CdS surfaces.

Gold nanoparticles have been found own broad applications in nanomaterials and nanobiotechnology for their specific physical characteristics. But generally, they are considered difficult to trap stably optical tweezers which still owing In this paper, numerical studies carried out show the influence of laser parameters on gold particles tweezers. For comparison, polystyrene nanobeads is also shown. The results that a stable needs strict choice power wavelength, even though more suitable than...

Gold nanoparticles are widely employed in nanomaterials, nanobiotechnology and health care, but generally they considered difficult to trap stably. Compared with the continuous laser which is popular optical trapping, pulse has a relatively larger power its work pulse, useful for particles. So this paper comprehensively analyzes forces (the radiation forces, gravitation, Brownian motion) on gold tweezers formed by laser, through building up mathematical model. Finally gets dependence...

This paper analyzes the modality of two-dimensional photonic crystal micro-resonators by adopting equivalent refractive index mode. In this paper, it controls optical field distribution only through altering thickness light guide layer, while parameter like resonator structure and lattice arrangement remain stable. It discusses that would arrive at a satisfactory photon locality layer material is gallium nitride , its 2.1.This reveals influence micro-resonator layer’s towards modality,...

Particles with different reflective indices will receive radiation forces scale. The are very important to the technology of optical tweezers. As people know index is defined by permittivity material. So this paper theoretically studies influence nanoparticle on trapping performance tweezers, and finally gives relation curves between particle.
It is easier to obtain high energy in very short period through pulse laser than continuous laser. And the field of biology, especially researching active cells by optical tweezers, traditional employed tweezers are inclined hurt even kill cells. So, substituting pulsed one probable trend for tweezers. This paper theoretically analyzes radiation forces on nanoparticles and respectively, compares those two cases, obtains simulation curves forces.
