摘要
对以有机材料酞菁铜的LB薄膜作覆盖层的K^+离子交换玻璃光波导,进行了高速光学双稳特性研究.利用比较波导的输入和输出光脉冲形状法,在532nm光波长得到开关时间为24ps的高速光学双稳特性.
The 34 layers tapCuPo, the copper tera-4- ( 2.4-ditert-ampylphenoxy) phtha-locyanine, were deposited by the LB technique on the optical glass waveguide of K+ ion-exchange, and a four-layer dielectric waveguide with LB films cladding is formed. The 532 nm line from a YAG laser is used as a light source. The input light with pulse width of 250 ps is coupled into the optical waveguide by a glass prism, and then is passed through the regiod coated with the LB films. In the experiment,a fast optical bistability with the swithching off time to 24 ps has been demonstrated.
