Engineering photonic density of states using metamaterials
The photonic density of states (PDOS), like its electronic counterpart, is one of the key physical quantities governing a variety of phenomena and hence PDOS manipulation is the route to new photonic devices. The PDOS is conventionally altered by exploiting the resonance within a device such as a microcavity or a bandgap structure like a photonic crystal. Here we show that nanostructured metama...
متن کاملTopologically protected states in active photonic metamaterials
Background: A topologist is sometimes described as a mathematician who cannot discriminate between a tea cup and a doughnut. This means that topology focuses on global properties such as connectedness instead of geometrical detail, thereby paving the road for a new level of understanding. Topological invariants such as the Euler characteristic for surfaces in R are naturally quantized and do no...
متن کاملPhotonic metamaterials
The invention of metamaterials prompts reconsideration of a number of fundamental physical phenomena and enables a variety of unique properties and functionalities. These include negative refractive index, magnetism at optical frequencies, sub-wavelength resolution, “backward” phase matching conditions for nonlinear optical processes, and even rendering objects invisible – cloaking. In this bri...
متن کاملSelf-protected polariton states in photonic quantum metamaterials
We investigate the single-photon transport properties of a one-dimensional coupled cavity array (CCA) containing a single qubit in its central site by coupling the CCA to two transmission lines supporting propagating bosonic modes with linear dispersion. We find that even in the nominally weak light-matter coupling regime, the transmission through a long array exhibits two ultra-narrow resonanc...
متن کاملPhotonic density of states of two-dimensional quasicrystalline photonic structures
A large photonic band gap (PBG) is highly favorable for photonic crystal devices. One of the most important goals of PBG materials research is identifying structural design strategies for maximizing the gap size. We provide a comprehensive analysis of the PBG properties of two-dimensional (2D) quasicrystals (QCs), where rotational symmetry, dielectric fill factor, and structural morphology were...
