Optomechanically-induced transparency (OMIT) and the associated slowing of light provide the basis for storing photons in nanoscale devices. Here we study OMIT in parity-time (PT)-symmetric microresonators with a tunable gain-to-loss ratio. This system features a sideband-reversed, non-amplifying transparency , i.e., an inverted-OMIT. When the gain-to-loss ratio is varied, the system exhibits a transition from a PT-symmetric phase to a broken-PT-symmetric phase. This PT-phase transition results… 

Tunable slow and fast light in parity-time-symmetric optomechanical systems with phonon pump.

A tunable switch between slow and fast light effect is realized by adjusting the gain-to-loss ratio, power of the control field as well as the amplitude and phase of the phonon pump.

Loss-induced transparency in optomechanics.

It is found that optical transparency can emerge at the otherwise strongly absorptive regime in the OMIT spectrum, by using an external nanotip to enhance the optical loss.

Tunable multi-channel inverse optomechanically induced transparency and its applications.

This work describes a feasible inverse OMIT in a multi-channel fashion with a double-sided optomechanical cavity system coupled to a nearby charged nanomechanicals resonator via Coulomb interaction, where two counter-propagating probe lights can be absorbed via one of the channels or even via three channels simultaneously with the assistance of a strong pump light.

Electromagnetically induced transparency and slow light with optomechanics

Measurements at room temperature in the analogous regime of electromagnetically induced absorption show the utility of these chip-scale optomechanical systems for optical buffering, amplification, and filtering of microwave-over-optical signals.

Loss-induced suppression and revival of lasing

Overturning conventional wisdom that loss is bad and should be minimized, Peng et al. show that carefully tweaking the coupling strength between the various components of a coupled optical system can actually result in an enhancement of the optical properties by adding more loss into the system.

Parity–time synthetic photonic lattices

The experimental observation of light transport in large-scale temporal lattices that are parity–time symmetric is reported and it is demonstrated that periodic structures respecting this symmetry can act as unidirectional invisible media when operated near their exceptional points.

Optomechanically Induced Transparency

Electromagnetically induced transparency in an optomechanical system whereby the coupling of a cavity to a light pulse is used to control the transmission of light through the cavity may help to allow the engineering of light storage and routing on an optical chip.

PT-symmetric phonon laser.

The PT-symmetric phonon laser with balanced gain and loss is introduced by introducing gain to one of the microcavities such that it balances the passive loss of the other, resulting in a highly efficient phonon-lasing action.

Signatures of nonlinear cavity optomechanics in the weak coupling regime.

It is shown that if the strong laser drive is detuned by half the mechanical frequency, optomechanically induced transparency also occurs due to resonant two-photon processes, and this effect provides a new method of measuring the average phonon number of the mechanical oscillator.
