| 摘 要： | 本文用质子交换反应在5mol％MgO:LiNbO_3晶体中引起了e光折射率的增加,晶体中MgO的存在并不影响LiNbO_3质子交换光波导阶跃型折射率分布的特点。用常规的质子交换法制备的MgO:LiNb·O_3波导存在着损耗大和有效折射率不稳定的缺点,经过退火处理后,这些缺点可明显地得到改善。

| Abstract: | Proton-exchange process causes the increase of extraordinary refractive index in 5 mol% MgO:LiNbO3 crystal, and the existence of MgO does not affect the step-like index profile of LiNbO3 proton-exchanged waveguide. Large propagation lose and instabilities of effective index are present in MgO-doped waveguides fabricated by conventional proton-exchange process, but these drawbacks can be aparently improved by post-annealing treatment. |
