Herein, for the first time, a sensitive sensing platform rapid detection of microRNA was developed by employing black phosphorus nanosheets as fluorescence quenching material.
A super-oscillation far-field focusing micro-lens based on continuous amplitude modulation is experimentally demonstrated with 40-nm thick width-varied sub-wavelength metallic slit array. The 228 × 200 μm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> designed and fabricated numerical aperture 0.976 focal length 40.1λ for wavelength λ = 632.8 nm. Experimental results show that the ~26.5 ± 1 μm, line full width at half maximum 0.379λ,...
Metasurfaces offer promising structures for controlling the wavefront of light. The development such is evidence numerous ways to alter on demand light properties as amplitude, phase, and polarization. However, simultaneous control all parameters over a wide bandwidth still great challenge. With polarization multiplexing, we have achieved lesser goal phase amplitude 1000 nm using plasmonic nanoslit array associated with traditional detour phase. In proof-of-concept experiment, demonstrate 3D...
Optical traps use focused laser beams to generate forces on targeted objects ranging in size from nanometers micrometers. However, for their high coefficients of scattering and absorption, micrometer-sized metallic particles were deemed non-trappable three dimensions using a single beam. This barrier is now removed. We demonstrate, both theory experiment, three-dimensional (3D) dynamic all-optical manipulations gold under focusing conditions. The force gravity found balance the positive...
Since the discovery of graphene, its excellent physical properties have greatly improved performance optoelectronic devices and brought important technological advances to optical research applications. Here, graphene is introduced field optical-tweezer technology demonstrate a new graphene-based opto-thermoelectric tweezer. This not only reduces incident light energy required by two orders magnitude (compared with traditional tweezers), it also brings advantages such as much broader working...
Surface-enhanced Raman spectroscopy (SERS) technology usually uses metallic nanoparticles to enhance scattering signals, thereby significantly adding molecule-level recognition and detection. However, realization of nanometer-scaled SERS imaging in liquid environments is extremely difficult due the requirements both precise scanning single nanoparticle high enhancement field thus has never been achieved before. To overcome this obstacle, we demonstrate an immersive mapping technology, based...
Strong plasmonic focal spots, excited by radially polarized light on a smooth thin metallic film, have been widely applied to trap various micro- and nano-sized objects. However, the direct transmission part of incident leads scattering force exerted trapped particles, which seriously affects stability trap. Here we employ novel perfect beam solve this problem. Both theoretical experimental results verify that such could strongly suppress directly transmitted reduce piconewton force, an...
Measuring phase and polarization singularities of light individually or simultaneously.
Developing color image sensors with miniaturization and high-resolution as goals brings challenges to conventional filters that, by absorbing out-of-band light, have low light transmission resulting from separation. The emergence of nanophotonic splitters full-band offers an alternative solution. For the Bayer array imaging sensor, we demonstrate numerically experimentally a splitter via introducing optimization algorithm based on path information in inverse design. device has total...
Polarization imaging finds applications in many areas, such as photoelasticity, ellipsometry, and biomedical imaging. A compact, snapshot, high-efficiency polarimeter is highly desirable for applications. Here, based on a single multifunctional geometric phase optical element (GPOE), new method proposed snapshot polarimetry. With tailored spatially varying orientation of each anisotropic unit cell, the GPOE works efficiently both spin sorter half-wave plate, enabling retrieving full Stokes...
As a tool in the manipulation of micro- and nano-objects, optical tweezers are found applications many areas. However, selective trapping still poses challenges. Recently, meta-surface technique offers an approach to improve capabilities. Here, we demonstrate metallic nanoparticles with tailored plasmonic fields using polarization sensitive metalens. We show, both by theory experiments, modulated antitrapping forces when beam polarizations tuned. Combining effects two orthogonal circular...

The optical tweezers (OT) use force to trap micro/nano particles. This technology has widely been employed in manipulating cells, viruses and atoms, etc. Optical fiber (OFT), as a novel type of OTs, possess excellent characteristics easy fabrication, strong anti-interference ability, high compatibility with chip devices, flexible operation compact structure. Usually, the OFT probes are tapered, but they have low strength, which makes it difficult capture smaller particles (sub-micron size)....
