Abstract
Disordered photonic materials, like milk, white paint, and paper, are opaque and usually white. Light propagating through these materials is scattered multiple times and diffuses through the medium. The diffusion of light is treated using a theoretical framework based on Green’s functions and multiple scattering. An important concept in multiple scattering of light is the transport mean free path, which is the average distance light travels through the medium before becoming fully diffuse. In this presentation, I will introduce the recent progress in the fundamental research and the application research on the multiple light scattering. Wavefront shaping technique for focusing light through and inside disordered photonic materials as one of the applications is discussed.
Who is the guest lecturer?
Dr. Muhammad Danang Birowosuto was born in Jakarta, Indonesia, in 1980. In 2007, he received his PhD degree in Applied Physics from Delft University of Technology, The Netherlands for his work on cerium doped materials in the search for high-light-yield and fast-response scintillators for X-ray, gamma-ray, and thermal neutron detection. He has authored 22 international journal papers and 2 international patents from this research. Since February 2008, he is working as a postdoctoral researcher in the group of Complex Photonic Systems (COPS) at University of Twente, The Netherlands. His current research interests include multiple light scattering, local density of states fluctuations in random photonic media, and spontaneous emission of single emitter.
