The optics and applications of graphene oxide

Civilisations are advanced by both incremental developments, such as miniaturisation, and quantum leaps such as the Industrial Revolution. Silicon, as the principal material for semiconductor devices, has not only dominated the material science, but shaped the engineering counterparts. However, the use of silicon in photonics has been restricted due to its large footprint, opaqueness, and time-consuming manufacturing. This thesis presents innovative research on the optics and applications of graphene oxide and reduced graphene oxide by using the direct laser printing method, providing indispensable for the next generation highly efficient, integratable, ultralight weight, and flexible optical systems towards various multidisciplinary applications.
