Abstract
We study numerically depressed-index cladding, buried, micro-structured optical waveguides that can be formed in a lithium niobate crystal by femtosecond laser writing. We demonstrate to which extent the waveguiding properties can be controlled by the waveguide geometry at the relatively moderate induced refractive index contrasts that are typical of the direct femtosecond inscription.
摘要
我们对通过飞秒激光写入可在铌酸锂晶体中形成的低折射率包层、掩埋式微结构光波导进行了数值研究。我们展示了在直接飞秒写入典型的相对适中的诱导折射率对比度下，波导几何结构能在多大程度上控制波导特性。
