200031, Researchers led by Professor Baohua Jia at Swinburne University of Technology, Victoria, Australia, Professor Cheng-Wei Qiu at National University of Singapore, Singapore and Professor Tian Lan at Beijing Institute of Technology, Beijing, China considered the generation of super-resolved optical needle and multifocal array using graphene oxide metalenses. Ultrathin and lightweight, metalenses are becoming increasingly significant for their use in photonic chips, biosensors and micro imaging systems such as smart phone cameras. Compared to conventional lenses, metalenses can improve the image quality of current cameras, by enhancing resolution and removing spherical and chromatic aberrations. A single ultrathin (less than the thickness of 1/100 of a human hair) metalens element can be used instead of the multiple element imaging systems required by conventional lenses. Due to the unique light-matter interaction in a confined 2D plane, 2D materials are ideal for use with metalenses, further reducing the required thickness of the lens. 2D Graphene family materials, for example graphene oxides, are air-stable, have many applications and are low-cost and easy to fabricate in large scale. They remain stable in extreme environments, for example lower earth orbit in aerospace, so have potential use in satellites replacing the current bulky lenses and improving imaging quality and lowering launch costs.
