有机染料掺杂薄膜的光谱和双稳特性研究

Spectra and Optical Bistability Study of Organic Dye Embeded Thin Film

摘要:

制备了有机染料Eosin掺杂PVA聚合物薄膜,并实验研究了它的光谱特性和非线性光学特性,从理论上分析了这种掺杂薄膜的双稳产生机理。用Ar~+激光514.5nm线、实验测得其开关阈值功率约40mW,开关时间约200μs。

Abstract:

The nonlinear optic and spectra of thin film of saturable dye Eosin embeded in polyvingl alcohol (PVA) are reported, Experiments are performed using the 514.5 nm line of an Ar~+laser, we studied the optical distability, and gave the switching time and energy.
