High-resolution light field prints by nanoscale 3D printing
John You En Chan, Qifeng Ruan, Menghua Jiang +5
A light field print (LFP) displays three-dimensional (3D) information to the naked-eye observer under ambient white light illumination. Changing perspectives of a 3D image are seen…
Painting with Hue, Saturation, and Brightness Control by Nanoscale 3D Printing
Hao Wang, Qifeng Ruan, Hongtao Wang +7
Varying only the in-plane or out-of-plane dimensions of nanostructures produces a wide range of colourful elements in metasurfaces and thin films. However, achieving shades of grey…
Fabrication Development of a Large Area Grating for Out of Plane Beam Coupling
Jonathan Trisno, Tong Hua Lee, Parvathi Nair S. +5
We develop a single-layer waveguide surface grating structure to vertically couple near infrared (NIR) light at ~1.55 um wavelength from a large area (~100 um length scale) Si wave…
Structural Multi-Colour Invisible Inks with Submicron 4D Printing of Shape Memory Polymers
Wang Zhang, Hao Wang, Hongtao Wang +9
Four-dimensional (4D) printing of shape memory polymer (SMP) imparts time responsive properties to 3D structures. Here, we explore 4D printing of a SMP in the submicron length scal…
