Title

Non-Hermitian Microring Systems: Pt-Symmetric Lasers, Mode Management And Enhanced Emission Efficiency

Abstract

We provide an overview of our recent work on PT-symmetric microring lasers and present our newest theoretical findings and experimental results on mode control and lasing dynamics in such configurations. In contrast to conventional approaches, the exceptional-point dynamics arising from the complex interplay of gain and loss allow for the suppression of parasitic resonances with virtually no detrimental effects on the overall system efficiency. Finally, we show how PT-symmetrically structured active materials can serve as a powerful tool to tailor the modal content of lasing emissions from larger-area transversely multimoded architectures.
