TY - JOUR T1 - Birefringence Properties and Surface Relief Grating Formation on Methylacrylate Polymers with Photochromic Side Chains TT - JF - ijop JO - ijop VL - 4 IS - 1 UR - http://ijop.ir/article-1-38-en.html Y1 - 2010 SP - 23 EP - 30 KW - Surface relief grating KW - lightinduced birefringence KW - methylacrylate polymers KW - photoisomerization N2 - We have studied light-induced birefringence (LIB) and surface relief grating (SRG) formation in the series of methylacrylate polymers. The effect of material structure such as length of photochromic side chain, glass transition temperature and molecular structure of azo units on LIB and SRG are studied. The optical formation of self-induced SRG on films of these materials is also presented. M3 ER -
