Complete and absolute photonic bandgaps in highly symmetric photonic quasicrystals embedded in low refractive index materials
It is firmly established that periodic lattice structures can support photonic bandgaps (PBG). However, complete and absolute photonic bandgaps (CAPBG) have only been achieved in high dielectric constant mediums such as GaAs (o=13.6). An artificial quasiperiodic photonic crystal based on the random square-triangle tiling system was designed and fabricated. The photonic quasicrystal possesses 12...
متن کاملZero phase delay in negative-refractive-index photonic crystal superlattices
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 interf...
متن کاملDirac directional emission in anisotropic zero refractive index photonic crystals
A certain class of photonic crystals with conical dispersion is known to behave as isotropic zero-refractive-index medium. However, the discrete building blocks in such photonic crystals are limited to construct multidirectional devices, even for high-symmetric photonic crystals. Here, we show multidirectional emission from low-symmetric photonic crystals with semi-Dirac dispersion at the zone ...
متن کاملBand Structure and Dispersion Properties of Photonic Quasicrystals
In this paper, for developing analytical and semi-analytical methods to evaluate band structure in photonic quasicrystals the perturbation theory is examined. It is shown that more isotropic and complete photonic band gap can be observed under low dielectric contrast for photonic quasicrystals in comparison with ordinary crystals and because of this feature of photonic quasicrystals, perturbati...
متن کاملNear - zero refractive index photonics
The control and manipulation of light on the nanoscale — the primary aim of nanophotonics — is of fundamental scientific interest and plays a key role in telecommunication technologies and energy management. Yet, because light–matter interactions are usually weak and hard to confine, they often need to be assisted by the use of suitably designed macroscopic media. For instance, the use of caref...
