Abstract Ring cavities are quickly emerging as preferential platforms to investigate spontaneous symmetry breaking. However, research on handedness polarisation splitting within Kerr-coupled cavities is yet at a preliminary stage. Here, we observe ex

In linear optical processes, compact and effective wavefront shaping techniques have been developed with the artificially engineered materials and devices in the past decades. Recently, wavefront shaping of light at newly generated frequencies was al

A nonlinear coupled heterostructure, metal-nonlinear-metal-insulator-metal, is proposed. The heterostructure is a non-Hermitian system that possesses reciprocal and nonreciprocal optical transmission characteristics. With low incident power, linear o

In this work we theoretically study the exceptional points and reflection spectra characteristics of a grating coupled metal-insulator-metal heterostructure, which is a non-Hermitian system. Our results show that by selecting suitable geometrical par

A series of truxene-containing alkynylplatinum(II) terpyridine complexes has been designed and synthesized, with their UV–vis absorption and emission properties determined. The two-photon absorption and two-photon induced luminescence properties fo

Developing semiconductors with wide tunable gain bandwidth have always been at the forefront of laser technologies. The variation in feedback resonators can provide a useful tool for producing a relatively wide range of discrete lasing wavelengths. H

The frequency-upconverted fluorescence and stimulated emission induced by multi-photon absorption (MPA) have attracted much interest. As compared with low-order MPA process, the construction of high-order MPA process is highly desirable and rather at
