摘　　要：The realization of hybrid optics could be one of the best ways to fulfll the technological requirements of compact,light-weight,and multi-functional optical systems for modern industries.Planar diffractive lens(PDL)such as diffractive lenses,photonsieves,and metasurfaces can be patterned on ultra-thin flexible and stretchable substrates and be conformally attached on top of arbitrarily shaped surfaces.In this review,we introduce recent research works addressed to the design and manufacturing of ultra-thin graphene optics,which will open new markets in compact and light-weight optics for next-generation endoscopic brain imaging,space internet,real-time surface proflometry,and multi-functional mobile phones.To provide higher design flexibility,lower process complexity,and chemical-free process with reasonable investment cost,direct laser writing(DLW)of laser-induced-graphene(LIG)is actively being applied to the patterning of PDL.For realizing the best optical performances in DLW,photon-material interactions have been studied in detail with respect to different laser parameters;the resulting optical characteristics have been evaluated in terms of amplitude and phase.A series of exemplary laser-written 1D and 2D PDL structures have been actively demonstrated with different base materials,and then,the cases are being expanded to plasmonic and holographic structures.The combination of these ultra-thin and light-weight PDL with conventional bulk refractive or reflective optical elements could bring together the advantages of each optical element.By integrating these suggestions,we suggest a way to realize the hybrid PDL to be used in the future micro-electronics surface inspection,biomedical,outer space,and extended reality(XR)industries.
