Tunable multi-channel inverse optomechanically induced transparency and its applications

Area of Science:

• Quantum Optics
• Optomechanics
• Nanotechnology

Background:

• Conventional optomechanically induced transparency (OMIT) typically involves light transmission.
• Inverse OMIT, however, exhibits coherent absorption phenomena in optomechanical systems.
• Understanding inverse OMIT is crucial for novel light-matter interactions.

Purpose of the Study:

• To characterize a feasible inverse OMIT in a multi-channel optomechanical system.
• To explore the absorption of probe lights via single or multiple channels.
• To investigate the potential for detecting energy dissipation and relative phase.

Main Methods:

• Utilizing a double-sided optomechanical cavity coupled to a charged nanomechanical resonator via Coulomb interaction.
• Employing two counter-propagating probe lights and a strong pump light.
• Simulating realistic conditions with slightly different nanomechanical resonators.

Main Results:

• Demonstrated the feasibility of inverse OMIT in a multi-channel optomechanical system.
• Showcased absorption of probe lights through one or three channels simultaneously.
• Confirmed the possibility of detecting energy dissipation.
• Identified conditions for unilateral inverse OMIT and precise relative phase detection.

Conclusions:

• The proposed model provides a feasible platform for studying inverse OMIT.
• The system allows for multi-channel coherent absorption and precise phase detection.
• This research opens avenues for novel applications in quantum information and sensing.
