Femtosecond Optical Trap-Assisted Nanopatterning through Microspheres by a Single Ti:Sapphire Oscillator

Abstract: A new approach for fabricating a range of patterns using femtosecond optical trap-assisted nanopatterning is presented. We report how a single Gaussian laser beam from a 55 fs, 80 MHz, 780 nm Ti:sapphire oscillator trapping dielectric microspheres near surfaces can be used to enable near-field, direct-write, subwavelength ∼λ/6 (∼130 nm), two-dimensional nanopatterning of a polymer surface. We discuss the stability conditions for effective manipulation of the particle by the pulsed beam. Klein−Kramers and Brown… Show more

“…The most common approach consists of physically moving the microparticle in the XY plane. Several methods have been developed to achieve such physical displacement, including mechanical [ 62 , 66 , 67 , 68 ], optical [ 20 , 69 , 70 ], and chemical forces [ 71 ]. Among the mechanical ones, mounting a microsphere into the cantilever of an atomic force microscope, or AFM, offers unsurpassed positioning control [ 68 ].…”

“…By using a nanosecond pulsed laser, coaxial with the Bessel beam, this method enables the ablation of arbitrary polymeric patterns with a minimum size of ~100 nm (<λ/3). The experimental setup can be simplified if the same pulsed laser is used for trapping and ablation [ 69 ]. For glass substrates, a post chemical etching of the laser-irradiated regions can be used to further reduce the minimal size to 70 nm (λ/11) [ 70 ].…”

“…The current problems in microscopy, nanostructuring, and nanolithography require various approaches to enter under the diffraction limit. For example, multiphoton absorption of an illuminated sample is widely used [1,2]. Another way is to obtain a localization of the electromagnetic field in the near zone of the scatterer.…”

“…Photonic nanojets attract a continuously growing interest as a potential tool for operation with concentrated light forms under the diffraction limitation. Most of the studies in this area are directed to the formation of PNJ by light diffraction on dielectric microspheres [2][3][4][5][6][7][8][9][10][11][12][13][14] and on microcylinders [15][16][17]. There are also studies devoted to other forms of scatterers, for example, microaxicons [18] or microdisks [19].…”

“…For the historical review, algorithms, and approaches, see [6]. Nowadays, GLMT is widely used owing to the exploitation of microbeads in various areas, for example, an ultralow-threshold Raman laser can be based on dielectric microbeads [5], photonic nanojets are formed when a plane wave is diffracted by a dielectric microbead [7][8][9], etc. Another reason is that the spherical GLMT model can be the first-order approximation for the theory of scattering by nonspherical objects.…”
