We propose a scheme that can generate tunable double optomechanically induced transparency in a hybrid optomechanical cavity *** this system, the mechanical resonator of the optomechanical cavity is coupled with an additional mechanical resonator and the additional mechanical resonator can be driven by a weak external coherently mechanical driving *** show that both the intensity and the phase of the external mechanical driving field can control the propagation of the probe field, including changing the transmission spectrum from double windows to a *** study also provides an effective way to generate intensity-controllable, narrow-bandwidth transmission spectra, with the probe field modulated from excessive opacity to remarkable amplification.

We study the generation of quadruple-transparency windows and the implementation of a conversion between slow and fast light in a hybrid optomechanical system. By demonstrating the generation of these transparency windows one by one, we analyze the physical mechanism through which each transparency window forms in detail. Additionally, we discuss how the system parameters affect the formation of transparency windows and conclude that the location, width, and absorption of each transparency window can be arbitrarily manipulated by varying the appropriate parameters. Moreover, when the pump field is changed from red to blue detuning, conversions between slow and fast light occur in the output field. These interesting properties of the output field can be applied to achieve the coherent control and manipulation of light pulses using cavity optomechanical system.

We propose a scheme for realizing the optical nonreciprocal response based a four-mode optomechanical system,consisting of two charged mechanical modes and two linearly coupled optical modes. Two charged mechanical modes are coupled by Coulomb interaction, and two optical modes are coupled to one of mechanical modes by radiation pressure. We numerically evaluate the transmission probability of the probe field to obtain the optimum optical nonreciprocal response parameters. Also, we show that the optical nonreciprocal response is caused by the quantum interference between the optomechanical couplings and the linearly coupled interaction that breaks the time-reversal symmetry.

We propose how to achieve quantum nonreciprocity via unconventional photon blockade(UPB) in a compound device consisting of an optical harmonic resonator and a spinning optomechanical resonator. We show that, even with very weak single-photon nonlinearity, nonreciprocal UPB can emerge in this system, i.e., strong photon antibunching can emerge only by driving the device from one side but not from the other side. This nonreciprocity results from the Fizeau drag, leading to different splitting of the resonance frequencies for the optical counter-circulating modes. Such quantum nonreciprocal devices can be particularly useful in achieving backaction-free quantum sensing or chiral photonic communications.

Recently,optomechanical systems have emerged as promising platforms to perform quantum information processing .There has been considerable progress in the control of solid-state phonons at the quantum level,including the ground state cooling ,the generation of quantum correlated states between radiation fields and mechanical motion ,and mechanical squeezing . A unique feature of the optomechanical systems is the interconversion between stationary and flying (photonic)*** motion can serve as a universal transducer to mediate the long-range interactions between stationary quantum systems, including trapped ions,superconducting circuits,single charges,and spins in diamond or silicon ,enabling the construction of a hybrid quantum network that combines the otherwise incompatible degrees of the freedom of different physical systems.

Two azobenzene compounds,Disperse Red 1(DR1)and 4-aminoazobenzene(Aazo),were separately linked to poly(acrylic acid)(PAA)side chains to form PAA-DR1 and PAA-Aazo,which were then associated with poly(ethylene oxide)(PEO)to produce hydrogen-bonded polymer complex *** UV irradiation,the initial modulus and yielding strength of PAA-Aazo/PEO fiber were both increased tremendously,while the mechanical properties of PAA-DR1/PEO fiber only slightly *** drawn and dried in vacuum,PAA-DR1/PEO and PAA-Aazo/PEO fibers with an extended length exhibited a contraction of 20%and 25%under UV irradiation,showing potential for photo-actuation.
