Abstract: The present disclosure provides an integrated infrared circular polarization detector with a high extinction ratio and a design method thereof. The detector structurally includes a metal reflective layer, a bottom electrode layer, a quantum well layer, a top electrode layer, and a two-dimensional chiral metamaterial layer. Under circularly polarized light with the selected handedness, surface plasmon polariton waves are generated at the interface between the two-dimensional chiral metamaterial layer and the semiconductor, and has a main electric field component aligned with the absorption direction of the quantum wells, thereby enhancing the absorption of the quantum wells. Under circularly polarized light with the opposite handedness, since most of the optical power is reflected, surface plasmon polariton waves cannot be effectively excited, and the absorption of the quantum wells is extremely low, thus realizing the capability of infrared circular polarization detection with a high extinction ratio.
