Abstract:

Three-dimensional nanofabrication of complex structures out of multiple materials remains a challenge. Better approaches can enable new materials, microfluidic biosensors, and photonic devices. Here I present an optical positioning and linking (OPAL) approach for assembling 3D structures out of large numbers of multi-material microscale and nanoscale building blocks. This optical tweezers-based approach provides a route for fabricating structures that were previously infeasible, including precision augmentation of microscale optical devices. Novel computational approaches that we have developed for designing new photonic devices based on the assembly of discrete building blocks will also be discussed.

Biography:

Euan McLeod is an Associate Professor in the Wyant College of Optical Sciences at the University of Arizona (UA) as of August 2021. He is also an Associate Professor of the UA BIO5 Institute and an Affiliate Member of the UA Cancer Center. Euan is a Senior Member of both the Optical Society of America and SPIE. He won an NSF CAREER award in 2021. Euan is a member of the Conference on Lasers and Electro-Optics (CLEO) subcommittee on Light-Matter Interactions and Materials Processing, as well as the IEEE Electron Devices Technology and Manufacturing (EDTM) Conference in the areas of Photonics, Imaging, and Display. Euan’s background and interests lie at the intersection of optics, nanoscience, and soft bio-materials science. He has published more than 35 papers on these topics in peer-reviewed journals and has been awarded 5 patents, with major contributions in the areas of high-speed varifocal lenses based on acoustic modulation; lensfree holographic imaging of nanoparticles, viruses, and biomarkers; and the use of optical tweezers in fabricating micro- and nano-structured materials. The tunable acoustic gradient index (TAG) lenses co-invented by Euan received numerous innovation awards, including: a 2013 R&D 100 Award; a 2013 SPIE & Photonics Media: Prism Award; and a 2017 Thomas Alva Edison Patent Award. This patented technology is now fully licensed by Mitutoyo Corp and commercially sold.
