dc.description.abstractFocusing performance of Peano space filling curve-based fractal construction is studied at communication wavelength of 1550 nm. Lensing by diffraction from these finite-sized 2D devices of the first three iterated fractal lattice system constructed with gallium-doped zinc oxide is computationally demonstrated in a systematical manner. In this regard, focusing performance parameters such as efficiency, spot size, focal length, focal depth, and fill-factor are determined on the basis of geometrical parameter sweep and fractal generation through finite difference timedomain simulations. Focusing efficiency from 48% up to 60%, absolute efficiency from 14% up to 33.98%, numerical aperture values from 0.127 up to 0.96, spot sizes from 1.02 lambda SP up to 11.25 lambda SP, and focal depth larger than focal length are introduced by all computational samples. A conformal Talbot effect is assigned when appropriate geometric values are provided. A novel perspective is offered by a newly adapted fractal lattice to optics via an alternative plasmonic material perspective, especially for an optical fiber component.en_US
