Interferometric femtosecond laser processing for nanostructuring inside thin film

• Stephen Ho

  Stephen Ho is a postdoctoral fellow at the University of Toronto. His interest in Biomedical Engineering led him to study Engineering Science at the University of Toronto and received his B.A.Sc. degree in 2002. He furthered his studies and he received his M.A.Sc. degree (2005) and PhD (2013) in Electrical and Computer Engineering under the Photonics Group at the University of Toronto. The title of Stephen’s thesis was ‘Femtosecond Laser Microfabrication of Optofluidic Lab-on-a-Chip with Selective Chemical Etching’. Stephen now continues his research interest and works on femtosecond laser micro and nano-machining, laser fabrication of optofluidic lab-on-a-chip and 3-D structures inside transparent dielectric materials.

  , Kitty Kumar

  Kitty Kumar is a postdoctoral fellow at Harvard University. She earned her first MSc in the Department of Physics at Panjab University, India. Her fascination with manipulating materials at nano-scale to change their properties for a broad range of applications by using fundamental science and advance tools led her earn second MSc degree in Physics at Memorial University, Canada followed by PhD in Materials Science and Engineering at the University of Toronto. She is focused on developing new techniques for engineering materials for various applications and understanding the underlying physical phenomenon. The title of her PhD thesis is “High performance inverted pyramidal texture for silicon photovoltaics”. She now continues her research at Harvard University on bioinspired materials.

  Kenneth K.C. Lee received his B.A.Sc. degree in Engineering Science from the University of Toronto in 2009. He is currently a PhD candidate in the Department of Electrical and Computer Engineering at the University of Toronto, Ontario, Canada. He is exploring ways to improve polymer-based micro-actuator and to fabricate compact fibre-optic sensors with femtosecond laser direct writing. The miniature and flexible polymer actuator and optical sensor will serve as building blocks to create an advanced steerable biomedical catheter for minimally invasive surgical procedures.

  Jianzhao Li received his BSc degree from Sichuan University, Chengdu, China, his MSc degree from Fudan University, Shanghai, China, and his PhD degree from the University of Electro-Communications, Tokyo, Japan. His research experience has covered laser, laser spectroscopy, nonlinear and quantum optics, laser material processing and micro/nano-fabrication. Currently he focuses on the mechanism study and application development of advanced laser micro/nano-fabrication assisted with 5-dimensional multimodal laser microscopy and spectroscopy. He is a member of OSA and SPIE.

  und Peter R. Herman

  Peter R. Herman received the B.Eng. degree (1980) in Engineering Physics at McMaster University. He earned M.A.Sc. (1982) and PhD (1986) degrees studying lasers and diatomic spectroscopy in the Physics Department at the University of Toronto followed with a post-doctoral position at the Institute of Laser Engineering in Osaka University, Japan (1987) to the study of laser-plasma physics and X-ray lasers. He joined the Department of Electrical and Computer Engineering at the University of Toronto in 1988 where he currently holds a full professor position. Professor Herman directs a large and collaborative research group that develops and applies laser technology and advanced beam delivery systems to control and harvest laser interactions in new frontiers of 3-D nanofabrication. This includes processing of optical materials aimed at lightwave circuits, microfluidics, optofluidic systems, biophotonic sensors, and smart medical catheters with end goals of new manufacturing processes towards the concepts of lab-on-a-fiber and lab-in-a-film microsystems. Our group has published more than 300 scientific journal and conference papers and generated 10 patents.
