Abstract
I report atypical transmission characteristics of a micro cavity supporting two degenerate modes with their mode-coupling subjected to non-Hermitian modulation. Such non-Hermitian time-Floquet systems allow for effective optical energy exchange between different Floquet modes enabling its utilization as both a frequency shifter and a frequency beam splitter. Additionally, depending on the driving signal parameters, the modes can be amplified compensating for insertion loss. I provide a detailed analytical framework to model the time-varying cavity and optimize its parameters for efficient performance. The reported results and analysis are expected to be valuable for applications in quantum photonics and optical communication.
期刊介绍:
IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
