Job description:

We are looking for creative and self-driven researchers to join our team to explore and push the boundaries in the fundamentals of 2D and 3D printed nano-optics for a broad range of applications. The project aims to develop (design, fabricate, and test) optical devices at nano/micro scale by means of high-resolution nanofabrication tools including 3D direct laser writing (two-photon polymerization lithography) and electron beam lithography. Successful candidates can expect excellent collaboration opportunities with reputable groups worldwide, be at the cutting edge in nanotech and photonics research, and receive competitive salary and staff benefits.

About our group

The Joel Yang group at SUTD is interested in the science and engineering of making small things and in using them to control light. How small? Between roughly 1 nanometer to several micrometers. Materials at these length scales interact with light in remarkable ways, not seen in the bulk. For instance, polished aluminum and silver are well known to be reflective metals in the bulk. But tiny little particles of the same materials start appearing colorful, with colors that depend sensitively on their actual size, shape, and arrangements. The result is a unique approach to produce colorful prints at unprecedented levels of detail. At 100,000 dots per inch (dpi), this method is a thousand times higher resolution than a desktop color printed. Importantly, the ability to generate colors on demand provides an appealing alternative to pigments and dyes that might be less sustainable.

Through advanced techniques in nanotechnology, we make nanostructures out of a broad range of materials. These materials range from metals such as gold, silver, and aluminum to transparent polymers, 2D materials and semiconductors like silicon. We have probed them with electron beams, shot pulses of energetic photons at them, and performed numerical simulations to investigate their behavior. The fascinating findings are reported in our research publications.

We believe in making the world a better place through our innovations in the field of nanotechnology. Utilizing the craft of miniaturization, we strive to make devices smaller, better, and faster.
