Single particle detection, manipulation and analysis with resonant optical trapping in photonic crystals.
We demonstrate a resonant optical trapping mechanism based on two-dimensional hollow photonic crystal cavities. This approach benefits simultaneously from the resonant nature and unprecedented field overlap with the trapped specimen. The photonic crystal structures are implemented in a 30 mm × 12 mm optofluidic chip consisting of a patterned silicon substrate and an ultrathin microfluidic membr...
متن کاملPatterned Optical Trapping with Two-Dimensional Photonic Crystals
We demonstrate an approach to achieve patterned optical trapping with two-dimensional photonic crystals (2D PC). A Gaussian beam infrared laser is guided and loosely focused by a simple optical system onto the surface of the 2D PC, which generates an enhanced diffraction field for optical trapping of microbeads with high efficiency. The diffraction patterns are determined by the structures of t...
متن کاملOptical trapping, Field enhancement and Laser cooling in photonic crystals.
We present a detailed study of the mode structure of inverse opal photonic crystal materials with an emphasis on their potential use in optical trapping and cooling. In particular, we analyze the modes corresponding to the upper and lower band edges of a high refractive index inverse opal, i.e., the so-called ;;air' and ;;dielectric' bands. In the dielectric band, we demonstrate optical intensi...
متن کاملResonant optical trapping in microfluidic-integrated hollow photonic crystal cavities
The recent years have highlighted the potential of photonic nanostructures to extend the capabilities of optical tweezers and to perform advanced optical manipulations. In this context, two-dimensional photonic crystal cavities have been regarded as promising candidates owing to their high quality factors and low mode volumes. The work presented in this thesis reports the setting up of a comple...
متن کاملThree-dimensional optical trapping and manipulation of single silver nanowires.
We report the first experimental realization of all-optical trapping and manipulation of plasmonic nanowires in three dimensions. The optical beam used for trapping is the Fourier transform of a linearly polarized Bessel beam (termed FT-Bessel). The extended depth of focus of this beam enables the use of a retroreflection geometry to cancel radiation pressure in the beam propagation direction, ...
