Improved Laser Induced Birefringence in Highly Doped Optical Polymers
Application of polymers in novel and advanced scientific technologies is increasingly expanding. In this regard, optical polymers among different materials have found a special and unique position. A novel dye doped polymer thin film was prepared by taking advantage of dye molecules' interaction with the host environment. This sample, like self-assembled structures, makes use of this interaction to increase the response intensity significantly, and thus improve the performance of photonic devices. This highly improved response is mainly due to the possibility of making highly concentrated dye doped polymeric samples. In this way, the function of optical polymers in photonic applications and its mechanism were studied. Laser induced birefringence and spectral measurements were used in these studies. Time dependencies of the sample were studied and no significant qualitative differences were observed. It was shown that highly doped samples perform their function qualitatively correct in nonlinear optical applications. Also, in comparison with the best international reports published in this field so far, a significant improvement in final results has been observed quantitatively. Overall, according to extensive spectral changes and markable induced birefringence, this method is known as an effective way to construct improved photonic devices.
