Dynamically tunable reflecting Near infrared band-pass filter based on hybrid graphene-nanometallic structure is demonstrated by numerical simulation. The proposed filter is constructed by unit cells with graphene monolayer embedded into the nanometallic grating structure. The gradual transition of graphene monolayer from very thin metal to dielectric play the key role to tune the reflection spectrum of the structure. Its frequency spectrum is also analyzed, which clearly shows a blueshift of passband with increasing graphene Fermi energy. The filter parameters are investigated by varying graphene Fermi energy through external voltage gates. The modulation depth, center frequency, bandwidth and quality factor of the filter could be tuned. We achieved stable modulation depth as high as 0.735, and quality factor as high as 3.4. The center frequency can be tuned in a broad range from 210 to 230 THz and bandwidth tuning from 60 to 95 THz. The effect of nanogap size and environment refractive index is also numerically investigated. These results are very promising for the future use and integration of the proposed filters as a key element of optical communication system and infrared sensing.
