Abstract

We present methods to realize nanoimprinted nanocomposite membrane-type metamaterials with tuned refractive index. Here, the idea is separation of the cured UV-curable resist from top and bottom stamps to make freestanding patterned membranes with controlled thickness. Manipulating the refractive index of the resist material is implemented by changing the volume fraction of nanoparticles in the host polymer. These patterned membrane devices are applied in guided-mode resonance devices exhibiting effective spectral signatures in subwavelength periodic media. We present numerous simulated and fabricated nanomembranes with excellent resonance characteristics.
