“…Cavity optomechanics is an emerging field exploring the interaction between light and mechanical motion in a cavity, which has found broad applications in testing macroscopic quantum physics, high-precision measurements, and quantum information processing [88][89][90][91][92][93]. The optomechanical interaction originates from the mechanical effect of light, i.e.…”

Electromagnetically induced transparency (EIT)is a quantum interference effect arising from different transition pathways of optical fields. Within the transparency window, both absorption and dispersion properties strongly change, which results in extensive applications such as slow light and optical storage. Due to the ultrahigh quality factors, massive production on a chip and convenient all-optical control, optical microcavities provide an ideal platform for realizing EIT. Here we review the principle and recent development of EIT in optical microcavities. We focus on the following three situations. First, for a coupled-cavity system, all-optical EIT appears when the optical modes in different cavities couple to each other. Second, in a single microcavity, all-optical EIT is created when interference happens between two optical modes. Moreover, the mechanical oscillation of the microcavity leads to optomechanically induced transparency. Then the applications of EIT effect in microcavity systems are discussed, including light delay and storage, sensing, and field enhancement. A summary is then given in the final part of the paper.

“…Cavity optomechanics, which explores the interaction between light fields and mechanical motion, has attracted much attention in the past few years for its potential application in the ultrasensitive detection of tiny masses, forces, and displacements [1][2][3][4][5]. One standard optomechanical setup, and the simplest, is a Fabry-Perot cavity in which one end mirror is a micro-or nanomechanical vibrating object [6][7][8].…”

We study optomechanically induced amplification and perfect transparency in a double-cavity optomechanical system. We find that if two control lasers with appropriate amplitudes and detunings are applied to drive the system, optomechanically induced amplification of a probe laser can occur. In addition, perfect optomechanically induced transparency, which is robust to mechanical dissipation, can be realized by the same type of driving. These results indicate important progress toward signal amplification, light storage, fast light, and slow light in quantum information processes.

“…A network of coupled oscillators can spontaneously synchronize, as was first reported for pendulum clocks hung from a common frame 14 and further observed in numerous biological systems including the flashing of fireflies and the chirping of crickets 15 . Alternatively, a single oscillator can synchronize to the phase of an externally applied drive in an effect known as injection locking, as has been studied extensively in the context of electrical tank circuits 7,16,17 , implemented in non-linear mechanical resonators 19 and further observed for the effect of light on human circadian rhythms 20 . Both these forms of synchronization have been explored in optomechanical systems.…”

Advances in optomechanics have enabled significant achievements in precision sensing and control of matter, including the detection of gravitational waves and the cooling of mechanical systems to their quantum ground state. Recently, the inherent non-linearity in the optomechanical interaction has been harnessed to explore synchronization effects, including the spontaneous locking of an oscillator to a reference injection signal delivered via the optical field. Here, we present the first demonstration of a radiation-pressure driven optomechanical system locking to an inertial drive, with actuation provided by an integrated electrical interface. We use the injection signal to suppress drift in the optomechanical oscillation frequency, strongly reducing phase noise by over 55 dBc/Hz at 2 Hz offset. We further employ the injection tone to tune the oscillation frequency by more than 2 million times its narrowed linewidth. In addition, we uncover previously unreported synchronization dynamics, enabled by the independence of the inertial drive from the optical drive field. Finally, we show that our approach may enable control of the optomechanical gain competition between different mechanical modes of a single resonator. The electrical interface allows enhanced scalability for future applications involving arrays of injection-locked precision sensors.
