Abstract

Tamm plasmon polaritons (TPPs) are localized photonic states at the interface between a metal layer and one-dimensional (1D) photonic crystal substrate. Unlike surface plasmon polaritons (SPPs), TPPs can be excited by both transverse magnetic and electric waves without requiring additional coupling optics. TPPs offer robust color filtering, making them ideal for applications such as complementary metal oxide semiconductor (CMOS) image detectors. However, obtaining a large-area, reversible, and reconfigurable filter remains challenging. This study demonstrates a dynamically reconfigurable reflective color filter by integrating an ultrathin antimony trisulfide (Sb2S3) layer with Tamm plasmonic photonic crystals. Reconfigurable tuning was achieved by inducing Sb2S3 crystallization and reamorphization via thermal and optical activation, respectively. The material exhibited good stability after multiple switching cycles. The reflectance spectrum can be tuned across the visible range, with a shift of approximately 50 nm by switching Sb2S3 between its amorphous and crystalline phases. This phase transition is nonvolatile and substantially minimizes the energy consumption, enhancing efficiency for practical applications. Tamm plasmonic photonic crystals are low-cost and large-scale production, offering a platform for compact color display systems and customizable photonic crystal filters for realistic system integration.
