Tapered fibers with diameters ranging from 1 to 4 μm are widely used to excite the whispering-gallery(WG)modes of microcavities. Typically, the transmission spectrum of a WG cavity coupled to a waveguide around a resonance assumes a Lorentzian dip morphology due to resonant absorption of the light within the cavity. In this paper, we demonstrate that the transmission spectra of a WG cavity coupled with an ultrathin fiber(500–700 nm)may exhibit both Lorentzian dips and peaks, depending on the gap between the fiber and the microcavity. By considering the large scattering loss of off-resonant light from the fiber within the coupling region, this phenomenon can be attributed to partially resonant light bypassing the lossy scattering region via WG modes, allowing it to be coupled both to and from the cavity, then manifesting as Lorentzian peaks within the transmission *** implies the system could be implemented within a bandpass filter framework.

自润滑青铜轴承的性能决定于许多因素的综合作用,诸如精整后的密度、径向压溃强度(RCS)、含油量、表面粗糙度、施加的载荷、轴的速度及孔隙结构。压坯与烧结体的密度以及烧结时的尺寸变化(DC),在轴承制造中都很重要。这篇文章阐述了生产高使用性能烧结轴承用的一系列新的青铜粉末。对使用性能的测定表明,与用标准的预混合青铜粉末制造的轴承相比,这些轴承摩擦系数较小,温升较低且稳定,而且径向压溃强度较高。性能优异是因为连通孔隙结构较细小,从而通过极好的毛细作用可吸入大量油。在理论上,较高的RCS可使轴承具有较高的承受载荷的能力。

NaYF_(4):Eu nanorods with high aspect ratios are elaborated and optically trapped using dual fiber optical tweezers in a counterpropagating geometry. High trapping efficiency is observed using converging beams, emitted from diffractive Fresnel lenses directly 3D printed onto cleaved fiber facets. Stable nanorod trapping and alignment are reported for a fiber-to-fiber distance of 200 μm and light powers down to 10 m W. Trapping of nanorod clusters containing one to three nanorods and the coupling of nanorod motion in both axial and transverse directions are considered and discussed. The europium emission is studied by polarization-resolved spectroscopy with particular emphasis on the magnetic and electric dipole transitions. The respective σ and π orientations of the different emission lines are determined. The angles with respect to the nanorod axes of the corresponding magnetic and electric dipoles are calculated. Mono-exponential emission decay with decay time of 4–5 ms is reported. It is shown that the nanorod orientation can be determined by purely spectroscopic means.

We have used a gold nanohole array to trap single polystyrene nanoparticles, with a mean diameter of 30 nm, into separated hot spots located at connecting nanoslot regions. A high trap stiffness of approximately 0.85 fN∕(nm·m W)at a low-incident laser intensity of ～0.51 m W∕μm^2 at 980 nm was obtained. The experimental results were compared to the simulated trapping force, and a reasonable match was achieved. This plasmonic array is useful for lab-on-a-chip applications and has particular appeal for trapping multiple nanoparticles with predefined separations or arranged in patterns in order to study interactions between them.
