We present a methodology and instrumentation scheme for patterning of diffractive optical elements (DOE) on graphene oxide (GO) thin-film. The proposed is based on direct laser writing (DLW) process using a femtosecond (Fs) pulse laser as the energy source. GO is a thin film of graphite that has...
