Enhanced spin hall effect of reflected light due to Optical Tamm states with Dirac semimetal at the terahertz range
Keqiang Yin, Luzihao Li, Qijun Ma +2
The enhanced photonic spin hall effect (PSHE) plays a positive role in the flexible manipulation of photons. Here, by combining Dirac semimetals with Bragg reflector constructed by…

Tunable optical bistability in grapheme Tamm plasmon/Bragg reflector hybrid structure at terahertz frequencies
Shenping Wang, Jiao Xu, Hongxia Yuan +4
We propose a composite multilayer structure consist of graphene Tamm plasmon and Bragg reflector with defect layer to realize the low threshold and tunable optical bistability (OB)…
