A multi-transparent-window regulation method based on a coupled-cavity optomagnetic mechanical system

Abstract

This invention discloses a method for controlling multiple transparent windows based on a coupled-cavity opto-magnetic-mechanical system, comprising the following steps: Step 1: Building a physical model of the coupled-cavity opto-magnetic-mechanical system, including a YIG crystal with a microbridge structure, a microwave cavity, and coupled dual optical cavities; Step 2: The coupled optical cavity and microwave cavity are driven by a strong red detuned optical field and a microwave field, respectively; Step 3: Introducing two weak detection fields at two frequencies to detect the output responses of the two cavity modes; Step 4: Solving for the output spectra of the microwave cavity and optical cavity using the Langevin equations of motion; Step 5: Changing the system coupling parameters to achieve the fabrication of multiple transparent windows, fast and slow light, and Fano resonance phenomena. This invention solves the technical challenge of multiple transparent window coexistence by implementing multiple coupling mechanisms in one system, and utilizes multi-band transparent windows to achieve discrete signal processing, supporting multi-band quantum storage and multi-channel photonic information processing, thereby improving the efficiency and capacity of quantum information processing.
