英文摘要	We propose an alternative method to realize broadband high contrast ratio optical diodes based on polarization conversion between transverse electric (TE) wave and transverse magnetic (TM) wave with two slabs of uniaxial hyperbolic crystal. Taking hexagonal boron nitride as an example of the crystal, our numerical simulation results show that asymmetric transmission can occur in the wavelength range from 6.40 to 7.38 mu m for incidence of a TM wave, and the transmissivity contrast ratio can be beyond 1000 in the wavelength range from 6.63 to 7.33 mu m. For incidence of a TE wave, the asymmetric transmission with the transmissivity contrast ratio higher than 1000 is found in the wavelength range from 12.33 to 12.88 mu m. Given that the structure is novel and simple, it may provide a promising prototype for designing high performance integrated photonic devices, such as optical logic gate and optical memory.; National Natural Science Foundation of China [51576004]; SCI(E); ARTICLE; 9; 123
