Zero phase accumulation in negative-index photonic crystal superlattices

Zero phase delay in negative-refractive-index photonic crystal superlattices Kocaman, Serdar; Hsieh, P.; McMillan, J.F.; Biris, C.G.; Panoiu, N.C.; Yu, M.B.; Kwong, D.L.; Stein, A.; Wong, C.W. (2011-08-01) We show that optical beams propagating in path-averaged zero-index photonic crystal superlattices can have zero phase delay. The nanofabricated superlattices consist of alternating stacks of negative index photonic crystals and positive index homogeneous dielectric media, where the phase differences corresponding to consecutive primary unit cells are measured with integrated Mach-Zehnder interferometers. These measurements demonstrate that at path-averaged zero-index frequencies the phase accumulation remai...
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...
Zero-knowledge range proofs and applications on decentralized constructions Günsay, Esra; Cenk, Murat; Department of Cryptography (2021-2-15) Appropriate, effective, and efficient use of cryptographic protocols contributes to many novel advances in real-world privacy-preserving constructions. One of the most important cryptographic protocols is the zero-knowledge proofs. The zero-knowledge proofs have recently gained the utmost importance in terms of decentralized systems, especially in the context of privacy. In many decentralized systems, such as electronic voting, e-cash, e-auctions, or anonymous credentials, the zero-knowledge range proofs ar...
