Advances in Fibers, Optical Sensors, Optical Communications and Networks: Proceedings of Photonics 2023, Volume 2

This book presents the proceedings of the Biennial Photonics Conference (Photonics 2023) held at IISc, Bengaluru on 5-8 July 2023. It covers topics across multiple areas of photonics, including established areas like optical communication and networks, quantum optics, ​non-linear and ultrafast photonics​, nanophotonics​, biophotonics and bioimaging, ​​photonic integrated circuits​, fibers and sensors, optical materials and fabrication techniques, optical metrology, and instrumentation, optofluidics, ​laser applications, ​optoelectronics. The book also covers emerging areas in photonics, such as THz photonics, structured Light, 2D materials, optomechanics, topological photonics, and AI/ML in photonics. The book will be useful for researchers and professionals interested in the broad field of photonics.

Varun Raghunathan received the Ph.D. degree in electrical engineering from the University of California Los Angeles, Los Angeles, CA, USA, in 2008, working in the area of silicon photonics. From 2009 to 2012, he was a Postdoctoral Scholar with the Department of Chemistry, University of California Irvine, Irvine, CA, USA, working in the area of nonlinear optical microscopy. He was a Research Scientist with Agilent Research Laboratories, working in the areas of Infrared micro-spectroscopy and applications of optical techniques to cancer imaging. He is currently an Associate Professor at the Department of Electrical Communication Engineering, Indian Institute of Science, Bangalore, India. His research group works in the areas of nonlinear optics, integrated photonics, resonant metasurfaces, optical communication, and quantum communications.

Tapajyoti Das Gupta obtained his B.Sc. and Btech in Physics and Radiophysics respectively from the University of Calcutta in 2006 and 2009. He then moved to France where he received his MSc in nanoscience from École Polytechnique (l’X) in 2012 and PhD in Condensed Matter Physics lab (PMC) from the same institute in 2015 under Prof. Thierry GACOIN and Alistair ROWE. He then joined Prof. Fabien Sorin’s Fiber Optics and Photonics Devices (FIMAP) lab in École Polytechnique Fédérale de Lausanne (EPFL) during 2015 December-2019 November. He also served in the Electrical Engineering department at the Indian Institute of Technology, Kanpur (IITK) for five months from January 2020 to May 2020, before joining the Department of Instrumentation and Applied Physics in July 2020. His research interest includes dynamic metasurfaces, optical instrumentation and soft robotics.

Sebabrata Mukherjee was awarded the B.Sc. in Physics from the University of Calcutta in 2010 and the M.Sc. in Physics from the Indian Institute of Technology Delhi in 2012. He undertook his Ph.D. at Heriot-Watt University, Edinburgh, in the area of experimental simulation of solid-state phenomena in photonic structures. He was subsequently awarded The 2016 MacFarlane Prize for the most outstanding contribution to the research at the University. He worked as a Research Associate and postdoctoral scholar at Heriot-Watt University and the Pennsylvania State University, USA, respectively. Sebabrata is an assistant professor in the Department of Physics at IISc Bangalore. His research interests include topological photonics, condensed matter physics, femtosecond laser writing, nonlinear optics, and periodically modulated systems.
