 High-quality optical ring resonators can confine light in a small volume and store it for millions of round trips, enabling the development of integrated photonic components in the visible and near-infrared spectral regions. However, the mid-infrared spectral region lags behind in development. This study demonstrates the integration of mid-infrared ring resonators and directional couplers with a quantum cascade active region in the waveguide core, allowing electrical control of the resonant frequency, quality factor, coupling regime, and coupling coefficient. The device can act as a tunable filter, non-linear frequency converter, or frequency comb generator depending on its operating point. The integration of multiple active resonators and waveguides allows for the implementation of purpose-specific mid-infrared active photonic integrated circuits for spectroscopy, communication, and microwave generation.
