Subwavelength Moiré Index Lens-Array – Flat, Ultra-Thin, Large NA, and Patterned by Large Area Nanoimprint Using a Mold Formed by Multiple-Double-Nanoimprint
The structure, fabrication, and demonstration of a new micro-lens-array, termed “subwavelength Moiré Index lensarray” (SMIL), that has a gradient optical index, in a ultra-thin (~100 nm) flat material layer, created by a subwavelength Moiré pattern resulted from superpositions of two or more periodic structures (e.g., grating or grid)
About Stephen Y. Chou
Stephen Y. Chou, Joseph C. Elgin Professor of Engineering at Princeton University, a member of National Academy of Engineering, and a fellow of IEEE, AVS, OSA, ISNM, Packard, and National Academy of Inventors, and a recipient of IEEE Brunetti Award, IEEE Nanotechnology Pioneer Award, Nanoimprint Pioneer Award, and other awards and honors.
Dr. Chou’s research over past 40 years covers several different fields: nanofabrication, nanoscale electrical, optical, magnetic, and biological devices, bioengineering, and medical diagnostics. His work and inventions have significantly impacted both academia and industry, and have created new research fields and new industries and business.
Dr. Chou’s most well-known invention and work is nanoimprint. He invented nanoimprint in 1995 and has, since, led a multidisciplinary team to develop nanoimprint tools, materials, processes, and applications. He and his team are the first to use nanoimprint to fabricate nanoscale electrical, optical, magnetic, and biological devices. The pioneering work by Dr. Chou and his team has played a key role in removing the doubts on nanoimprint in early days, and in creating the research and industry in nanoimprint. Dr. Chou founded the first nanoimprint equipment and material company – Nanonex Corp. with customers around globe, and the first company that uses nanoimprint to make subwavelength nanophotonic devices – NanoOpto Corp., and he co-founded with his students the first company that uses nanoimprint to make gene sequencing devices – BioNano Genomics Inc. He created the International Conference on Nanoimprint and Nanoprint Technology in 2001.
Other inventions and work by Dr. Chou include nanoscale wrap-around-gate transistors and single electron memories, lithographically-induced-self-assembly (LISA), single domain-patterned-media (quantized disk) – a new paradigm in magnetic data storage, new nanophotonics (e.g. subwavelength optics, ultra-sensitive Raman and fluorescence sensors, nanoplasmonic solar cells and LED’s), nanochannel single DNA molecule analyzer, a new ultra-sensitive biosensor (D2PA), and various mobile rapid health diagnostic technologies.
One of Dr. Chou’s latest work is his invention and development of a game-changing instant mobile health self-test platform – iMOST™ (Instant Mobile Self-Test), and founding and leading Essenlix Corp for R&D and commercialization of iMOS.. The iMOST platform is designed to make a layperson to self-perform a board range of diagnostic tests, easy, fast, anywhere, anytime, with results in ~60 sec, at low cost; and most importantly, accurate even using a simple device and under imperfect conditions (in sample, instruments, and operation).
