We propose and experimentally demonstrate a scheme of high-Q microwave photonic filter (MPF) using the techniques of self-phase modulation (SPM) spectrum broadening and third-order dispersion (TOD) com-pensation. The optical pulses from a mode-locking las
The synthesis of water-soluble quantum dots (QDs) has recently received extensive attention due to noninvasive detection of biological information in living subjects. In this paper, high-quality water-soluble (cadmium-free) quaternary AgZnInS QDs have bee
The nonmagnetic element Ca-doped LiNbO3 films were prepared on Si (111) substrates by radio frequency (RF) magnetron sputtering technique. X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) indicate that the Ca atoms enter the LiNbO3<
It is considered that three identical two-level atoms are separately trapped in three coupled single-mode optical cavities, and each atom resonantly interacts with cavity via a one-photon transition. The tripartite entanglement dynamics among atoms is stu
