Your library or personal account may give you access

Abstract

A photothermally tunable diffraction grating incorporating two grating patterns was inscribed by femtosecond laser on photothermal actuator composed of graphene oxide and polydimethylsiloxane layers. Tailoring light stimulus can induce different diffraction patterns in contactless way.
