Multiple optical trapping based on high-order axially symmetric polarized beams

Abstract

Multiple optical trapping with high-order axially symmetric polarized beams (ASPBs) is studied theoretically, and a scheme based on far-field optical trapping with ASPBs is first proposed. The focused fields and the corresponding gradient forces on Rayleigh dielectric particles are calculated for the scheme. The calculated results indicate that multiple ultra-small focused spots can be achieved, and multiple nanometer-sized particles with refractive index higher than the ambient can be trapped simultaneously near these focused spots, which are expected to enhance the capabilities of traditional optical trapping systems and provide a solution for massive multiple optical trapping of nanometer-sized particles.

Phase singularities of tightly focused high-order axially symmetric polarized beams in the focal region

“…RPBs have found wide applications in super-resolution imaging [13] , optical trapping [14] , particles acceleration [15] and near eld optics [16] due to these unique tight focusing properties. In addition, the tight focusing of high order ASPBs have also been studied due to some novel focusing properties [17][18][19] , such as multiple focal spots, which can be used in the multiple optical trapping [20,21] and parallel microscopy [22] .…”

Generation of light sheet focal patterns for light-sheet fluorescence microscopy via phase modulated radial and azimuthal variant vector beam

“…[36,40,41]. Simultaneously, higher order vector beams focused through a high NA lens produce ower-like patterns [42][43][44][45][46]. With appropriate pupil mask engineering, all of the previously mentioned vector elds can also generate light sheet focal patterns [15-17, 21-24, 29, 31-35].…”

Polarization-based control of spin-orbit vector modes of light in biphoton interference

“…The generation, measurement, and control of vector beams of light, whose transverse spatial and polarization degrees of freedom are nonseparable, have been the subject of a considerable amount of recent attention [1][2][3][4][5][6][7][8][9][10][11][12]. Applications of vector beams in classical optics include polarimetry [13,14], optical communication [15,16], kinematic sensing [17], and optical trapping [18][19][20][21]. Furthermore, the nonseparable nature of vector beams has allowed for experiments realizing local classical optics analogs to nonlocal quantum effects [22], including classical analogues to violations of Bell-like inequalities [23], the Hardy test [24], and quantum teleportation [25].…”
