摘要

The circular dichroism (CD) performance of conjugated gammadion structure on the end facet of silicon waveguide in the mid-infrared regime is investigated theoretically. By engineering the orientation of the structure, the sign and value of its CD spectrum can be changed. For a fixed gammadion structure, different CD values can be obtained not only by changing the excitation wavelength but the excitation waveguide mode. This finding potentially provides an extra degree of freedom to design integrated chiral photonics chips.
