The asymmetric transmission of electromagnetic waves refers to the difference in transmittance or polarization state when they pass through media from two opposite directions. This asymmetric transmission effect has potential applications in the integrated photonic system of optical communication, information processing and all-optical computing, and has been one of the important research topics. The traditional devices with asymmetric response are too bulky to meet the needs of the integration and miniaturization of modern optical devices. In recent years, much effort has been devoted to metasurfaces used to the design of asymmetric transmission devices. Due to its flat and ultra-thin features, metasurfaces have unique application prospects in miniaturized and integrated devices compared with traditional optical components.

On the Cover
At present, the environmental problems such as resource depletion, water pollution and air pollution caused by the development of nature resources have are raised great social concerns. Among the environmental issues, lighting electricity accounts for about 20% of global electricity consumption. Compared with traditional lighting sources such as incandescent lamps and fluorescent lamps, white light emitting diodes (LEDs) have many outstanding advantages like high energy efficiency, long working life, environmental friendliness, and etc. Therefore, the development of LEDs lighting is an effective solution to save power and protect the global environment.

In the development of topological photonics, robust propagation behaviors of topologically protected states in photonic analog of topological insulators have attracted broad attention. In the presence of dynamic time-dependent drivings, much more interesting topological phenomena are expected. Specifically, when the driving field is time-periodic, dynamic analogs of topological insulators, Floquet topological insulators FTIs, have been theoretically proposed in various dimensions. On the experimental side, researchers have already designed FTIs in cold atoms, photonic crystals and other systems. However, clear demonstrations of dynamic behaviors of FTIs have been rare, especially in one-dimensional systems, due to the lack of a flexible platform with easily tunable frequency and amplitude of the periodic driving field.

Thermal nanoimprint lithography, or nanoimprinting in short, is the process by which nano- and microscopic structures are transferred onto a material by heating it up to a specific temperature, such that it becomes malleable and can be molded into a desired shape. The technique has proven particularly useful for chalcogenide glasses due their low glass transition temperatures (e.g. 185 ºC), that allow for structuring of the glasses at temperatures that are easily obtained by conventional heaters. For this reason, thermal nanoimprinting has been applied in the fabrication of various photonic devices, including planar waveguides, diffraction gratings, and ring resonators.
