Abstract
In this paper we analyze the relationship between the spatial frequency response of focused surface plasmon with the birefringence of the sample. The sample consists of thin film of photo-addressable azobenzene functionalized homopolymer. Due to the photoisomerization of the cis-trans relaxation states of azopolymer, anisotropy is induced in the sample and absorption pattern with ellipticity of 1.082 is observed at the exit pupil plane. Quantitative analysis of the ellipticity and orientation of the absorption pattern reveals the magnitude of birefringence and direction of fast axis of the sample. Simulated and experimental results are presented.
