Abstract

All optical switching has been studied using the Optical Kerr Effect (OKE) configuration in a biopolymer matrix containing a photochromic molecule. The biopolymer system consisted of a deoxyribonucleic acid blended with cationic surfactant molecule cetyltrimethyl-ammonium chloride suitable for optical quality thin film fabrication. The excitation beams inducing birefringence were delivered from a continuous wave laser at 473 and chopped using a variable frequency chopper. Additionally auxiliary nanosecond pulses coming from Nd:YAG laser were used. The birefringence was instantaneously monitored by a weak non-absorbed light from a cw He-Ne laser working at 632.8 nm under crossed polarizer system. Excellent switching times in the range of microseconds and full reversibility of the studied processes have been observed.ïýïýïý
