Planar optical lenses are fundamental elements of miniaturized photonic devices. However,
conventional planar optical lenses are constrained by the diffraction limit in the optical far …

By decomposing a linearly polarized light field in terms of plane waves, the elliptic intensity
distribution across the focal spot is shown to be determined by the E-vector's longitudinal …

The fabrication method of the high-quality fiber microaxicons (FMAs) on the endface of the
optical fiber was developed. Using several types of the commercially available optical fibers …

subwavelenghth mictooptics element for polarization conversion from linear to radial”, Computer …

We propose and demonstrate a novel concept of a compact optical component aimed at
transforming a point-like source into a Bessel beam. This component, called AXIGRIN …

We present a quick, simple and accurate digital holographic characterization of the Bessel
beams produced by polymeric microaxicons. This technique allows the numerical …

Using a binary microlens of diameter 14 μm and focal length 532 nm (NA= 0.997) in resist,
we focus a 633 nm laser beam into a near-circular focal spot with dimensions (0.35±0.02) λ …

It is accepted so far that the formation of photonic nanojets requires the use of large
dielectric spheres (several wavelengths in diameter). Here we show both numerically and …

In this work, we demonstrate a simple setup to generate and measure arbitrary vector beams
that are tightly focused. The vector beams are created with a spatial light modulator and …

We show both numerically and experimentally that intense, narrow, and low-divergence
beams of light are produced at the apex of dielectric pyramid-shaped microtips. These …
