Optimization of highly circularly polarized thermal radiation in $\alpha$-MoO${}_3$/$\beta$-Ga${}_2$O${}_3$ twisted layers

Marco Centini, Chiyu Yang, Maria Cristina Larciprete +2

We investigate a bi-layer scheme for circularly polarized infrared thermal radiation. Our approach takes advantage of the strong anisotropy of low-symmetry materials such as $\beta$-Ga…
