Title: On-Chip Optical Spectroscopy:In SituandEx situmonitoring of chemical processes

Abstract:

Among analytical instruments, optical spectroscopy has unique capabilities of remote sensing of both chemical and physical parameters. It also greatly benefits from recent advances in MEMS and Microfluidics to enable extreme miniaturization and integration, also allowing to extend the spectral range from UV-visible to Near and Mid-Infra-Red, hence extending the measurement capabilities. Based on that, and considering the booming Internet-of-Things (IoT) era, such ultra-compact and low-cost spectrometers allows ubiquitous chemical sensing with several applications to environmental monitoring and healthcare, among the typical application areas considered in this talk. Another topic of interest is the on-chip monitoring of physico-chemical processes based on optical spectroscopy techniques, not necessarily using miniaturized spectrometers. In this case, the concern is thein-situprocess kinetics within the chip. Illustration is given of monitoring the growth and morphology of nanowires, their use for on-chip water purification as well as other emerging needs in water analysis.

Lecturer Introduction：

Tarik Bourouina holds M.Sc. in Physics, M.Eng. in Optoelectronics, Ph.D. in MEMS (1991), and Habilitation HDR (2000) from Université Paris-Sud, Orsay.

Tarik Bourouina took several positions in France and in Japan, at the Université Paris-Sud Orsay in 1995, at the French National Center for Scientific Research (CNRS) and at The University of Tokyo from 1998 to 2001.

Since 2002 he is full Professor at ESIEE Paris, Université Paris-Est. He used to be the Director of the joint Master dual-degree in MEMS Engineering between ESIEE Paris and NTU-Singapore from 2003 to 2007. Since 2008, he is acting as the Director of a Joint-Supervision PhD Program between Université Paris-Est and NTU-Singapore.

His entire career was devoted to the field of MEMS and Lab-On-Chip. He had several contributions in optical MEMS, among which the smallest MEMS-based FTIR Optical Spectrometer, NEOSPCTRA, jointly developed with Si-Ware-Systems, awarded the Prism award on photonics innovation in 2014. In 2017, he was the recipient of the Chinese Academy of Sciences President’s Fellowship, as visiting scientist at the Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP).His current interests include fundamental micro-opto-fluidics and micro- nano-structured materials, also seeking applications in the areas of Sustainable Environment and Smart-Cities.

Among his contributions to the scientific community, Dr. Bourouina served in the Technical Program Committee of IEEE MEMS from 2012 to 2013. He is now serving as an Editor in two journals of Springer-Nature Group:‘Light: Science and Applications’and‘Microsystems and Nanoengineering’.
