Heterogeneous Photonic Integration: Enabling Next-Gen Optical Circuits for Communication, Sensing, and Imaging

Join us for an insightful webinar with Dr. Samir Ghosh, researcher at the Irish Photonic Integration Centre (IPIC), Tyndall National Institute, as he explores the frontier of heterogeneous photonic integration. With a rich international background, Dr. Ghosh brings a global perspective to advancing photonic integrated circuits (PICs).

His current research focuses on integrating diverse material platforms—such as InP, GaAs, LiNbO₃, and garnet—on silicon to enable compact, fully functional PICs for applications in optical communication, sensing, and imaging. In this session, Dr. Ghosh will share technical insights into the challenges and breakthroughs in bonding dissimilar materials and achieving device-level integration of functionalities like modulation, nonreciprocity, and beam steering.

The talk will also reflect on his recent work in heterogeneous photonic integration, illustrating the evolution of integrated photonics over the past decade.

About the Presenter: Samir Ghosh from Tyndall National Institute 

Samir Ghosh joined IPIC at Tyndall in October 2020. He is a Researcher working with the III-V Materials and Devices group. His current research focus is on the heterogeneous integration of various optical materials, such as InP, GaAs, LiNbO3, and Garnet, for realizing fully functional photonic integrated circuits for communication, sensing, and imaging applications. He has (co-) authored 30 publications in refereed journals and in conference proceedings. He is one of the coordinators of the IPIC heterogeneous integration theme.

Samir obtained his Ph.D in Photonics Engineering from Ghent University-IMEC, Belgium in 2013. During his doctoral study he worked on integrated optical isolator and circulator for silicon photonics platform. Afterwards, he has spent several years as a postdoctoral researcher at various academic institutes around the globe, including McGill University (Canada), University of California – Davis (USA), The University of Tokyo (Japan), Nanyang Technological University (Singapore). He worked on diverse topics in integrated photonic systems, including optical nonreciprocity, silicon photonic modulators for short-reach communication, optical phased arrays for non-mechanical beam steering, and on-chip polarization detection and manipulation.
