Abstract Topological photonics provides a powerful framework to describe and understand many nontrivial wave phenomena in complex electromagnetic platforms. The topological index of physical system is an abstract global property that depends on the family operators describes propagation Bloch waves. Here, we highlight there profound geometrical connection between physics theory mathematical sur...

Abstract Multimode devices and components have attracted considerable attention in the last years, different research topics themes emerged very recently. The multimodality can be seen as an additional degree of freedom designing devices, thus allowing for development more complex sophisticated components. propagation modes used to increase fiber optic capacity, but also introduce novel intermo...

We discuss the development of quantum optical coherence tomography (Q-OCT), an imaging modality with a number of potential applications. Although Q-OCT is not expected to replace its eminently successful classical cousin, optical coherence tomography (OCT), it does offer some advantages as a biological imaging paradigm. These include greater axial resolution and higher signal-to-background rati...

Recent progress in direct laser writing of three-dimensional (3D) polymer nanostructures for photonics is reviewed. This technology has reached a level of maturity at which it can be considered as the 3D analogue of planar electron-beam lithography. Combined with atomic-layer deposition and/or chemical-vapor deposition of dielectrics—the 3D analogues of planar evaporation technologies, the 3D p...

Silicon photonics has become one of the major technologies in this very information age. It has been intensively pursued by researchers and entrepreneurs all over the world in recent years. Achieving the large scale silicon photonic integration, particularly monolithic integration, is the final goal so that high density data communication will become much cheaper, more reliable, and less energy...

Ultrafast Photonics Nanomaterials with remarkable optical properties including carbon-based, typical two-dimensional, and metal-based nanomaterials have been widely used in ultrafast photonics over the years. In article number 2200386, Bo Fu, Han Zhang, co-workers review applications, parameters of lasers, features each nanomaterial, further development photonics.
