Nanometallic antenna-assisted amorphous silicon waveguide integrated bolometer for mid-infrared.

Optics Letters, 2021
Bolometers are thermal detectors widely applied in the mid-infrared (MIR) wavelength range. In an integrated sensing system on chip, a broadband scalable bolometer absorbing the light over the whole MIR wavelength range could play an important role.
