Optoelectronic application of graphene nanoribbon for mid-infrared bandpass filtering

In this study, an ultra-compact optoelectronic bandpass filter is proposed. A single piece of graphene nanoribbon (GNR) is placed between two input-output GNRs to form a Fabry-Perot-like cavity. The GNR, as a mid-infrared surface waveguide, enhances the compatibility with complementary metal oxide-s...
