SiGeSn alloys have attracted considerable attention as a versatile group-IV material system for optoelectronic devices. Compared to the group III-V materials, SiGeSn holds advantages on CMOS compatible, low-cost, large wafer size (8-12 inches), high-volume manufacturing, etc. The direct bandgap GeSn as the gain medium is particularly advantageous for achieving the monolithic integration of laser on Si (Fig. 1). The novel laser solution promises a significant advance in Si photonics, which is extensively applied in applications such as data communication and 3D sensing.

Spotlight on Optics
Parity-time (PT) symmetry, as a physical concept, describes the special and temporal symmetry of the physical quantity. Recent year, it has been discovered that PT symmetry can be easily observed in the photonics system. Exceptional point (EP) is a particular point in the PT symmetric system, at which the eigenvalues and eigenvectors degenerate. Plenty of counterintuitive phenomena have been observed around EP. Specially, owing to the non-Hermiticity induced nonadiabatic transitions, chiral mode switching was achieved by encircling the exceptional point (EEP) in a PT symmetric system.

Optical tweezers (OTs) provide a powerful tool for trapping, guiding, and assembly of biological nanoparticles and cells, thus playing a unique role in biomedical and photonics areas. Particularly, OTs have been widely used to explore the structure, mechanism, and interaction of cells due to their ability of non-contact and high-resolution manipulation.
