Traditional optical systems are affected by diffraction limit which its focal spot size is limited by the incident wavelength and numerical aperture of the system. In 1987, Durnin and the coworkers firstly demonstrated the concept of nondiffr

We developed a new mechanical configuration which combines various optical techniques to maximize dynamic range and to optimize resolution in optical instruments. We assessed various optical configurations by looking at such variables as electronic s

The textured microstructures and the photonic nanostructures for light trapping structures are discussed. The inverted pyramidal microstructures with and without the tips were fabricated, and their light trapping performances were measured by the ref

We investigated the process of focusing a radially polarized (RP) light beam through a sub-wavelength annular aperture (SAA). We found that the result was a non-diffraction doughnut-shaped light beam which propagates in free space. After analyzing th

We propose a direct experimental set-up to observe the directional beaming effect of surface plasmon. A single diffracted beam from an asymmetric-sided surface corrugation is demonstrated. A single subwavelength slit with an asymmetric structure was

We examined the optical properties such as propagation modes, focal length, side lobes, etc. of metallic subwavelength annular apertures (SAA) and used finite-difference time-domain (FDTD) simulation to compare our experimental findings. Using two di

We focused the radial polarized light beam onto a sub-wavelength annular aperture (SAA) and compared the characteristics of SAA and traditional objective lens. We propose that SAA is a continuous numerical aperture optical element.

We investigated the optical properties of metallic sub-wavelength annular apertures (SAA). We found that cylindrical surface plasmons (CSP) not only increase optical transmission, but they help to focus the sub-wavelength and create a non-diffracting

We experimentally examined the near-field and far-field optical properties of a subwavelength annular aperture (SAA) made on silver film and undertook finite difference time domain simulations. In our near-field measurements, an interference pattern
