Methods of fabricating infrared bandpass filters and infrared bandpass filters fabricated thereby. The methods include forming metallic and dielectric spacer layers on a mold that defines nanoscale-sized recesses or protuberances, depositing a stress-absorbing layer on the dielectric spacer layer opposite the mold, and applying a force to the stress-absorbing layer to peel a first intermediate structure comprising the metallic layer, the dielectric spacer layer, and the stress-absorbing layer from the mold. The stress-absorbing layer may be dissolved from the first intermediate structure with a solvent to define a second intermediate structure. The second intermediate structure may be transferred to a receiver substrate to define the IR bandpass filter. The recesses or protuberances of the metallic and dielectric spacer layers are configured to function as quasi-three-dimensional (quasi-3D) plasmonic metal-dielectric hybrid nanostructures.
