Abstract: This study investigates the conversion of microwave signals to optical frequencies and vice versa, utilizing atomic coherence control and gain-based nonlinear optics within a closed-loop quantum system. We implement this method to establish a three-level quantum system based on a nitrogen vacancy center crystal, owing to its exceptional properties. It has been demonstrated that bidirectional interconversion of microwave and light is possible in the closed-loop quantum system via cross-Kerr nonlinearity due to the scattering of the microwave into the light field, in multi-photon resonance condition. Our investigation delves into the underlying mechanisms and demonstrates that significant efficiencies can be achieved through careful engineering of the system parameters. The capability to convert microwave-to-visible and visible-to-microwave frequencies underscores the potential applications of this technology in quantum communications, radio-optical systems, security applications, radar technology and quantum information processing by superconducting circuits.
