摘要

II 型超晶格红外传感器在文章编号 2400374 中，Sang Jun Lee、Won Seok Chang 及其合作者利用纳米压印光刻技术制造了一种 II 型超晶格中波长红外光探测器，该探测器与纳米结构线栅偏振器无缝集成。利用飞秒脉冲激光对线栅偏振片的表面进行抛光，在最大限度地提高偏振效率（即消光比）的同时，显著降低了光学损耗。这一突破为下一代高性能红外成像系统铺平了道路，为中波红外探测带来了前所未有的革命性能力。

Realizing the High Efficiency of Type-II Superlattice Infrared Sensors Integrated Wire-Grid Polarizer via Femtosecond Laser Polishing (Adv. Mater. Technol. 22/2024)

Type-II Superlattice Infrared Sensors

In article number 2400374, Sang Jun Lee, Won Seok Chang, and co-workers fabricate a type-II superlattice mid-wavelength infrared photodetector, seamlessly integrated with a nanostructured wire grid polarizer using nanoimprint lithography. The surface of the wire grid polarizer is polished with femtosecond pulse laser, which dramatically reduces optical losses while maximizing polarization efficiency, known as the extinction ratio. This breakthrough paves the way for next-generation high-performance infrared imaging systems, revolutionizing MWIR detection with unprecedented capabilities.
