离子交换KTP晶体光波导及其各向异性波导性能研究
Ion-Exchanged KTP Optical Waveguides and Their Anisotropic Properties
摘要
采用离子交换法制备了Rb:KTP晶体光波导,在不同波长的耦合光下测量了TE和TM偏振波导模式的有效折射率,拟合了波导层折射率的余误差函数分布,证明了波导折射率增量的各向异性,给出了其色散关系;最后计算并讨论了Rb:KTP波导的扩散特性。
Abstract
Rb:KTP optical waveguides are fabricated using ion-exchanged method. The effective mode index under TE and TM polarizations are measured at different wavelengths of incident coupling light. The refractive index profiles are fitted to the error function. The index incrementS are anisotropic and their dispersive relations are given.The diffusion characteristics of KTP waveguides are calculated and discussed.
