Abstract Topological photonics provides a new degree of freedom to robustly control electromagnetic fields. To date, most established topological states in have been employed Euclidean space. Motivated by unique properties hyperbolic lattices, which are regular tessellations non-Euclidean space with constant negative curvature, the boundary-dominated proposed. However, limited highly crowded boundary resonators and complicated site couplings, insulator has only experimentally constructed...
The novel physics of twisted bilayer graphene has motivated extensive studies magic-angle flat bands hosted by moiré structures in electronic, photonic, and acoustic systems. On the other hand, bound states continuum (BICs) have also attracted great attention recent years because their potential applications field designing superior optical devices. Here, we combine these two independent concepts to construct a new state photonic crystal slab, which is called as quasi-BIC, numerically...
Abstract Robust Integrable Quantum Optical Sources, Constructed by Topological Boundary States, Are Crucial for the on‐chip Information Processing. However, Limited Bulk‐edge Correspondence, Implementation of Channels Necessitates a Substantial Number Bulk Sites, Which Notably Diminishes Ratio Ring Resonators to Generate Sources. How Achieve Topologically‐protected Sources With Extremely Enhanced Utilization Efficiency Remains Challenge. Here, First Realization Hyperbolic is reported,...
The strong absorption and reflection from atomically thin graphene nanoribbons has been demonstrated over the past decade. However, due to significant band dispersion of nanoribbons, angle incident wave remained limited a very narrow range. Obtaining with wide range angles layers an unsolvable problem. Here, we construct tunable moiré superlattice composed pair nanoribbon arrays achieve this goal. By designing interlayer coupling between two mismatched periods, flat bands localization their...
On-chip generation of optical frequency combs (OFCs) holds fundamental significance for a wide range applications, such as precision metrology, communications, and so on. Recent investigations have shown that OFCs can be generated in topologically coupled array ring resonators, providing novel avenue to engineer nested temporal solitons robust comb spectra. However, limited by the bulk-edge correspondence, implementation topological always requires substantial number auxiliary bulk...
