Special Issue Information

Dear Colleagues, 

The exploration of the materials world at micro- or nanoscale asks for significant manipulation technologies to control nanomaterials in precise and versatile manner. Optical manipulation in regarded as one of the most promising platform due to non-contact interaction, high accuracy, and flexibility in light management. Physically, optical manipulation arises from the optomechanic coupling during the light-matter interaction, which includes direct momentum transfer between photons and nanomaterials and multiple-field coupling to convert optical energy to mechanical energy. The response of nanocrystals to the light-generated force field provides opportunities to trap or actuate the nanocrystals for a variety of applications in functional photonic devices, biosensing and nanomedicine. The present special issue on “Frontiers of Optomechanics of Nanocrystals” will summarize the most recent progress in this field, including but not limited to optical trapping, optical levitation, optical micromachines, optical printing, and optical assembly, as well as their cutting-edge applications. We expect that this special issue will provide new guidance for the design of optomechanic nanosystems for future technical innovation and applications.

We theoretically investigate the optomechanically induced transparency (OMIT) phenomenon and the fast and slow light effects of a four-mode optomechanical system with the Kerr medium. The optomechanical system is composed of an array of three single-mode cavities and a mechanical oscillator. The three cavities are a passive cavity, a no-loss-gain cavity and a gain optical cavity, respectively. A Kerr medium is inserted in the passive cavity. We study the influence of the Kerr medium on the stability of the optomechanical system, and find that the stable regime of the optomechanical system can be adjusted by changing the Kerr coefficient. We demonstrate that the phenomenon of optomechanically induced transparency will appear when the Kerr medium exists in the optomechanical system and find that the frequency position of the absorption peak on the left increases linearly with the Kerr coefficient. In addition, we also investigate the fast and slow light effects in this system. The results show that we can control the fast and slow light by adjusting the Kerr coefficient, tunneling strength, and driving field strength. This study has potential application prospects in the fields of quantum optical devices and quantum information processing. Full article
