Reciprocity is a fundamental principle in optics, requiring that the response of a transmission
channel is symmetric when source and observation points are interchanged. It is of major …

A recent renaissance in Brillouin scattering research has been driven by the increasing
maturity of photonic integration platforms and nanophotonics. The result is a new breed of …

Theoretical models of critical mass have shown how minority groups can initiate social
change dynamics in the emergence of new social conventions. Here, we study an artificial …

Brillouin laser oscillators offer powerful and flexible dynamics as the basis for mode-locked
lasers, microwave oscillators, and optical gyroscopes in a variety of optical systems …

Highly selective and reconfigurable microwave filters are of great importance in radio-
frequency signal processing. Microwave photonic (MWP) filters are of particular interest, as …

Electromagnetically induced transparency provides a powerful mechanism for controlling
light propagation in a dielectric medium, and for producing slow and fast light …

High-and ultrahigh-Q whispering-gallery mode resonators have the capability to trap
photons by total internal reflection for a duration ranging from nanoseconds to milliseconds …

In the past decade there has been a surge in research at the boundary between photonics
and phononics. Most efforts have centred on coupling light to motion in a high-quality optical …

Narrow linewidth visible light lasers are critical for atomic, molecular and optical (AMO)
physics including atomic clocks, quantum computing, atomic and molecular spectroscopy …

Abstract Both Kerr and Raman nonlinearities are radically enhanced by tight optical-mode
confinement in nanoscale silicon waveguides,,,. Counterintuitively, Brillouin nonlinearities …
