Microlasers have experienced tremendous development in the past decade and become an
essential part in laser evolution, as miniature lasers provide strong optical confinement and …

The law of momentum conservation rules out many desired processes in optical
microresonators. We report broadband momentum transformations of light in asymmetric …

Optical microresonators 1, which confine light within a small cavity, are widely exploited for
various applications ranging from the realization of lasers 2 and nonlinear devices 3, 4, 5 to …

We study in detail a novel type of optical nanoantennas made of high-permittivity low-loss
dielectric particles. In addition to the electric resonances, the dielectric particles exhibit very …

Whispering gallery mode (WGM) optical microresonators have attracted intense interests in
the past decades. The combination of high quality factors (Q) and small mode volumes of …

Optical whispering‐gallery mode (WGM) microcavities featuring ultrahigh Q factors and
small mode volumes enhance significantly the interaction between light and matter …

Optical sensors represent a vitally important class of analytical tools that have been used to
provide chemical information ranging from analyte concentration and binding kinetics to …

Control coupling and synchronization of lasers has become increasingly attractive for their
applications in spectroscopy, imaging, sensing, secret communication, and optical networks …

Wave instability—the process that gives rise to turbulence in hydrodynamics—represents
the mechanism by which a small disturbance in a wave grows in amplitude owing to …
