Laser trimming of graphene oxide for functional photonic applications

Abstract

This article reviews the recent photonic applications on graphene oxide and reduced graphene oxide films via the direct laser printing method. Attention has been paid to the unique optical property modulations of graphene oxide films during the laser reduction process, which enable a wide range of functional photonic and optoelectronic devices. The exotic properties of graphene oxide during the laser reduction process, including the tunable dispersion relation, flexible patterning capability, surface functionalization possibility, wavefront shaping ability, and the mechanical robustness and strength, make it a promising integratable platform for the next-generation ultrathin, lightweight and flexible photonic and optoelectronic applications.

Tailoring pores in graphene-based materials: from generation to applications

“…67,[75][76][77] Due to these OCFGs, GO exhibits a series of distinguished properties. 67,75,[78][79][80][81] On one hand, GO can be readily dispersed in an aqueous medium and can form well-dispersed aqueous colloids without the help of any surfactants agents. 40,82 Therefore, solution based lm synthesis methods can be applied, such as ltration, spin-coating, drop casting and self-assembly.…”

Near-perfect microlenses based on graphene microbubbles

“…The laser irradiation leads to a reduction of GO via evolution of oxygen functional groups. 17,18 These evolved gaseous species 19,20 are trapped within the reduced GO, forming near-perfect microbubbles at precise locations [see Figs. 1(b)-1(d) and Sec.…”

Free-standing graphene oxide mid-infrared polarizers

“…10 Uniquely, the optical and electrical properties of GO have been precisely tailored by manipulating its sp 2 -hybridized domains during the reduction process, enabling various photonic and optoelectronic applications. [11][12][13][14][15][16][17] However, the current optical characterizations of GO have been limited in the visible or near-infrared (NIR) regimes by using the conventional approaches such as ellipsometry, picometry or microscopy. 18,19 The optical properties of GO in the MIR regime are less studied previously owing to the constricted selections of both the available MIR characterization approaches and the unrevealed material band models, which hampers its MIR photonic applications.…”
