Phase-change materials (PCMs) provide a specific combination of optical tunning properties. The binary semiconducting chalcogenide Sb₂S<>sub3 is considered one of the promising candidates; especially for its intrinsic high refractive index, low loss and wide bandgap properties in near infrared (NIR). Here, the Sb₂S<>sub3 transformation from amorphous to crystal state embedded between the distribute Bragg reflector (DBR) and metal layer. With the proposed design, phase-change Tamm plasmon–polariton (PC-TPP) resonance could be produce. The PC-TPP resonance has a 70 nm modulation in wavelengths. Also, the resonance achieves around 100 nm-shifted in NIR at the designed incident angle.
