Paper Abstract

Interferometric lithography is one of the techniques used to produce micro and nano-scale periodic patterns like gratings in polymers and other substrates of interest. In this work, holographic surface relief gratings are optically inscribed on spin coated azo-dye (NBD)-labeled phospholipid (phosphatidylcholine) thin films using a low-intensity (10 mW) 244 nm frequency-doubled Ar+ laser. A systematic study of growth and decay of phospholipid grating is reported.
