摘要

我们使用飞秒(fs)激光直接写入方法演示了基于亚微米氧化石墨烯(GO)薄膜的各种衍射光学元件。暴露在fs脉冲下的指定氧化石墨烯区域通过光还原转化为具有高光学吸光度的还原氧化石墨烯(rGO)。GO/rGO模式作为二元衍射元件。

Graphene-based ultrathin optical components printed by femtosecond laser direct writing method

We demonstrated various diffractive optical components based on a sub-micrometer graphene oxide (GO) film using a femtosecond (fs) laser direct writing method. The designated GO region exposed to the fs pulses is converted to reduced GO (rGO) with high optical absorbance via photoreduction. The GO/rGO pattern acts as a binary diffractive element.
