Zero average index design via perturbation of hexagonal photonic crystal lattice
Moradi, Shahram; GÖVDELİ, ALPEREN; Kocaman, Serdar (2017-11-01)
We study the effect of one-dimensional lattice compression on photoriic band diagram and apply it to form a superlattice in order to obtain zero-Ti gap. Modulated hexagonal lattice has the ability to provide both positive and negative effective refractive indices. We analyze the dispersion characteristics in case the positions of holes in the lattice are varied in the orthogonal direction of applied light direction. We then compare modified structures with the conventional lattice and study the influence of...
Zero-n gap design via modulation of hexagonal photonic crystal lattice
Moradi, Shahram; Kocaman, Serdar; Yüce, Emre; Department of Micro and Nanotechnology (2017)
We study the effect of disorder in the lattice on a photonic band diagram and apply it to form a superlattice in order to examine negative refractive index and finally obtain zero-ñ gap. In addition, the novelty of suggested modulated PhC introduces new ways of controlling light through the complicated lattices. The aim of this approach is to have a deep understanding of dispersion characteristics dependence on the lattice structure by comparing modified structures with conventional lattice types. We design...
Flexible waveguides with amorphous photonic materials
Sarihan, Murat Can; Yilmaz, Yildirim Batuhan; Erdil, Mertcan; Aras, Mehmet Sirin; Yanik, Cenk; Wong, Chee Wei; Kocaman, Serdar (2019-01-01)
Amorphous photonic materials offer an alternative to photonic crystals as a building block for photonic integrated circuits due to their shared short-range order. By using the inherent disorder of amorphous photonic materials, it is possible to design flexible-shaped waveguides that are free from restrictions of photonic crystals at various symmetry axes. Effects of disorder on photonic crystal waveguide boundaries have examined before, and it is shown that flexible waveguides with high transmission are pos...
Tunable integrated optical modulator with dynamical photonic band transition of photonic crystals
GÖVDELİ, ALPEREN; Kocaman, Serdar (2019-01-01)
A Mach-Zehnder Interferometer based optical modulator composed of photonic crystals as phase shifters is presented. The switching process relies on the phase modulation along the arms of interferometer resulted from the photonic band shift of the photonic crystal regions. A small bulk index change leads to a large effective index difference between two arms of the interferometer and a small foot-print device can operate as a modulator. Presented MZI-based optical modulator is shown to have tunable bandwidth...
Integrated optical modulators with zero index metamaterials based on photonic crystal slab waveguides
Yildirim, Mustafa; GÖVDELİ, ALPEREN; Kocaman, Serdar (2019-01-01)
A novel integrated optical modulator design is presented using zero index metamaterial-based Mach-Zehnder Interferometer with photonic crystal phase shifters. The phase modulation relies on the shift between the photonic bandgaps having non-zero and zero effective refractive indices. A small change in the bulk index results in an effective index change between the arms of the MZI due to the disturbance of the band structure. Thus, such a structure provides a new approach for phase modulation on integrated o...
