Coherent virtual absorption of light in microring resonators

Abstract

The authors investigate the process of virtual photon absorption in integrated photonic setups made of microring resonators. They show that by tailoring the temporal waveform of the input signal, it is possible to trap most of the incident energy inside the resonator with minimal leakage. This energy is then released once the input signal is switched off. The authors have also explored the robustness of this effect against various imperfections such as waveform mismatch and optical nonlinear effects.
