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.

Integrated infrared circular polarization detector with high extinction ratio and design method thereof

Runtime memory cell row defect detection and replacement includes detecting in a memory of a computer system operating in a runtime operating system mode, a defective row of memory cells having at least one defective cell. In response to the detection of the defective row, interrupting the operating system of the computer system and, in a runtime system maintenance mode, replacing the defective row of memory cells with a spare row of memory cells as a replacement row of memory cells. Execution of the operating system is then resumed in the runtime operating system mode Other aspects and advantages are described.
