A new photonic absorber for optical information systems with nanomechanical resonator is proposed. The photonic absorber was consisted of minimal optical Yagi-Uda nanoantenna to absorb specific wavelength. Our photonic absorbers were fabricated through reactive ion etching following electron beam lithography. The measured absorbance spectra were evaluated in our work.
