Dynamical dispersion engineering in coupled vertical cavities employing a high-contrast grating

Abstract Photon’s effective mass is an important parameter of an optical cavity mode, which determines the strength of light-matter interaction. Here, we propose a novel method for controlling the photon’s effective mass by using coupled photonic cavities and designing the angular dependence of the...
