We present an all-dielectric photonic crystal structure that supports two-dimensionally confined helical topological edge states. The topological properties of the system are controlled by the crystal parameters. An interface between two regions of d

PMMC is an excellent distal flap for closure of defects in neck and lower face. It doesn't give way easily even in post radiotherapy period. Diabetics have a tendency for flap necrosis.

Topological photonic structures exhibit chiral edge states that are robust to disorder and sharp bends. When coupled to quantum emitters, these edge states generate directional light emission that enables unprecedented control of interactions between

Here we demonstrate chiral light-matter interactions in a topological photonic crystal resonator. We achieve this by employing valley-Hall topological edge states to create a helical resonator at the interface of two topologically distinct regions.

Hybrid organic–inorganic perovskites containing Cs are a promising new material for light-absorbing and light-emitting optoelectronics. However, the impact of environmental conditions on their optical properties is not fully understood. Here, we el

Temporal multiplexing provides an efficient and scalable approach to realize a quantum random walk with photons that can exhibit topological properties. But two-dimensional time-multiplexed topological quantum walks studied so far have relied on gene

Synthetic dimensions provide a promising platform for photonic quantum simulations. Manipulating the flow of photons in these dimensions requires an electric field. However, photons do not have charge and do not directly interact with electric fields
