IEM Distinguished Lecturers Seminar: Femtosecond laser lithography: from industrial scale micro chemical reactors to large scale photonic integrated circuits
Abstract
We begin with the physics and technology of fabrication of industrial scale micro chemical reactors of ~100 mL level internal volumes which now have been widely used in pharmaceutical companies in China. Also, we show the fabrication of high speed electro-optic modulators and large scale photonic neural networks on thin film lithium niobate substrate both of which are of ultra-high tuning speed and efficiency, together with the high power erbium-doped waveguide amplifiers. Femtosecond laser lithography is now providing innovative products that exist only in dreams before and thus is radically changing the landscapes in industries such as fine chemicals, medicine, and photonic integrated circuits.

Ya Cheng is now a Professor of East China Normal University. He received his B. S.from Fudan University in 1993 and PhD from Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences in 1998. He is the founder of the CHENG YA Chips Lab which focuses on the development of advanced manufacturing technologies for chemical and photonic chips. He published more than 200 peer reviewed papers and given more than 150 invited talks at international conferences. He holds 8 US patents and more than 30 Chinese patents. He is an Optica Fellow and a Fellow of Institute of Physics, UK.
