Abstract:
Mid-infrared (MIR) supercontinuum generation (SCG) has emerged as a significant area of research, offering opportunities in various scientific and technological domains. We will first discuss our numerical study on highly nonlinear photonic crystal fibers to produce MIR SCG for potential applications for communications, imaging, spectroscopy, and optical coherence tomography. The second part of my talk will focus on space-time (ST) optics: a new structure of spatiotemporal light fields. The ST light sheet represents a category of pulsed optical fields that retain their structure without experiencing diffraction or dispersion. This one-dimensional (1D) ST light sheet is characterized by classical entanglement, a correlation between at least two non-separable intrinsic degrees-of-freedom. In particular, we show that 1D ST light sheets exhibit self-healing characteristics. The third and the last part of my talk will discuss our preliminary investigation using ST light sheets for imaging and biosensing. Our experimental findings demonstrate the capability of the ST light sheets to exhibit resistance in turbid environments such as biological tissues. The results of our work could be useful for a wide range of optical applications including bioimaging, communications, astronomy, and optical trapping. The talk will conclude with a brief discussion of some of the recent additional directions that we are exploring.

Bio:
Dr Mbaye Diouf is a Tenure Track Assistant Professor at the School of Physics and Astronomy at Rochester Institute of Technology RIT. Dr. Diouf received his master and PhD in physics from University of Cheikh Anta Diop UCAD, Senegal. During his PhD Dr Diouf conducting research in Higher School of Communication of Tunis, Tunisia in the field of highly nonlinear fiber optics for supercontinuum generation supported by International Centre for Theoretical Physics (ICTP). After completing his PhD, he served as a research fellow under the Fellowship Training and Research in Italian Laboratories (TRIL) program at ICTP in Trieste, Italy. He served for several years at the School of Engineering at Brown University in Rhode Island, USA, initially as a Postdoctoral Researcher and later as a Senior Research Associate. During this time, he played a pivotal role in the design and construction of the PROBE Lab, which he led almost single-handedly, while also training and mentoring many of the lab’s students. His current and future research will broadly target optics and photonics, including nonlinear optics, structured light, ultrafast optics, light sheet microscopy, multiphoton microscopy, optical sensing and supercontinuum laser sources. Dr. Diouf reviews regularly for journals such as Optics Letters, Optics Express, Applied Optics, Scientific Report, and Nature Photonics.
