Fractal zone plates for wideband imaging with low chromatic aberration and extended depth of field
Walter D. Furlan, Genaro Saavedra, Juan A. Monsoriu
Fresnel zone plates are diffractive elements that are essential to form images in many scientific and technological areas, especially where refractive optics is not available. One…
Lacunar fractal photon sieves
Fernando Gimenez, Walter D. Furlan, Juan A. Monsoriu
We present a new family of diffractive lenses whose structure is based on the combination of two concepts: photon sieve and fractal zone plates with variable lacunarity. The focusi…
Fractal photon sieve
Fernando Gimenez, Juan A. Monsoriu, Walter D. Furlan +1
A novel focusing structure with fractal properties is presented. It is a photon sieve in which the pinholes are appropriately distributed over the zones of a fractal zone plate. Th…
Zero permeability and zero permittivity band gaps in 1D metamaterial photonic crystals
Ricardo A. Depine, Maria L. Martinez Ricci, Juan A. Monsoriu +2
We consider layered heterostructures combining ordinary positive index materials and dispersive metamaterials. We show that these structures can exhibit a new type of photonic gap…
Fractal Photonic Crystal Waveguides
Juan A. Monsoriu, Carlos J. Zapata-Rodriguez, Enrique Silvestre +1
We propose a new class of one-dimensional (1D) photonic waveguides: the fractal photonic crystal waveguides (FPCWs). These structures are photonic crystal waveguides (PCWs) etched…
