本文提出了一种具有群延迟色散匹配的宽带薄膜分束器的一般设计方法。通过在涂层设计中考虑衬底色散，输入和输出的任何组合都可以表现出相同的透射和反射色散。作为一个具体的实现，从600到1500 nm的超宽带50：50分束器的飞秒激光应用的设计，制造和表征。
We present a general design strategy for a broadband thin-film beam splitter with matched group-delay dispersion. By taking the substrate dispersion into account in the coating design, any combination of input and output can show the same dispersion for transmission and reflection. As a specific implementation, an ultrabroadband 50:50 beam splitter from 600 to 1500 nm for femtosecond laser applications was designed, fabricated, and characterized.
