The curved space-time produced by black holes leads to the intriguing trap** effect. So
far, metadevices have enabled analogous black holes to trap light or sound in laboratory …

Abstract Whispering-gallery-mode (WGM) cavity is important for exploring physics of strong
light-matter interaction. Yet it suffers from the notorious radiation loss universally due to the …

Asymmetric microcavities supporting Whispering-gallery modes (WGMs) are of great
significance for on-chip optical information processing. We establish asymmetric …

We describe the construction of an optical-space, cylindrical black hole induced by high
pressure in a dense fluid. Using an approximate analogy between curved spacetime and …

We present a novel method for designing transformation optical devices based on
electrostatics. An arbitrary transformation of electrostatic field can lead to a new refractive …

In this paper, we make an analogy of the interior Schwarzschild metric from transformation
optics (we call the method transformation cosmology). It is shown that a simple refractive …

General relativity establishes the equality between matter-energy density and the Riemann
curvature of spacetime. Therefore, light or matter will be bent or trapped when passing near …

Microcavity photon dynamics in curved space is an emerging interesting area at the crossing
point of nanophotonics, chaotic science, and non-Euclidean geometry. We report the sharp …

Light propagation in non-Euclidean geometry has become a hot topic in recent years, while
transformation optics theory demonstrates unique advantages in this respect. A notable …

In recent years, optical fields on non-Euclidean geometry have become a hot topic. The
geodesic conformal transformation theory, linking curved surfaces with planar gradient …
