Paper Abstract

In this work, we investigated the diffraction of inverse-hemisphere shaped polymer grating. We fabricated an inverse-hemisphere- shaped grating structure using soft lithography of close-packed PS nanospheres that is easy and cost-effective method. Then the diffraction wavelength shift induced from lattice change was measured. The periodicity of the grating was tuned by swelling in acetone. The measurement results suggest that the device can be used as a strain gauge or a chemical sensor.
