Photonic Materials & Structures Group
Photonic materials can emit, detect, reflect, transmit, convert, manipulate, and control the light and therefore they become interests of our group. Here we aim to study the light-matter interactions in novel materials, such as perovskites and chalcogenides, and their related photonic structures.
For the structures, we first focus on the confinements through different simple forms, such as zero- (quantum dots), one- (nanowires), two- (thin film or monolayers), and three- (single crystals) dimensional structures. We also evaluate complex photonic structures, such as photonic crystals, plasmonic meta surfaces, and disorder.
Our works are not only related with fundamental research but also with applications particularly LEDs, lasers, and scintillators with their observations vary from ultraviolet-visible to telecommunication wavelength.

Danang Birowosuto is a research area leader of “Photonic Materials” in Łukasiewicz – PORT. He received his Master and PhD degrees from University of Groningen and Delft University of Technology, respectively. After graduation, he was appointed as a postdoctoral researcher at University of Twente, Netherlands, and then, a researcher at Nippon Telephone Telegraph, Japan. In both places, he was active in research of Photonics and Nanotechnology with major interests including luminescence, scintillation, disordered materials, photonic crystals, plasmonic antennas, single photon sources, lasers, and telecom wavelength applications. Prior the position at Łukasiewicz – PORT, he joined CNRS International-NTU-Thales Research Alliance, Singapore, as principal researcher and program manager. There, he pioneered projects on perovskite halide scintillators and perovskite photonics. In total, he has 5 World and US patents with more than 100 journals (h-index 28). He is a member of many academic societies and also an active journal referee like in Nature, Optical Society, and American Chemical Society.

Somnath Mahato, Ph.D., Senior Research Engineer
Somnath Mahato a senior research engineer at “Photonic Materials and Structures” research group in Łukasiewicz – PORT. He obtained his PhD degree in October 2016 from Indian Institute of Technology (ISM) Dhanbad, India. During PhD, he developed Crystalline Silicon Solar Cell (HIT Solar Cells) using different transition metal oxides and conducting polymers as a hole transport layer at UPC Barcelona, Spain. Then he move to SINP, Kolkata, India as research associate and explored structural evaluation by grazing incidence X-ray scattering (GISAXS/GIWAXS) and X-ray reflectivity (XRR) using Synchrotron beam line sources at Photon Factory, KEK, Japan and Elettra, Italy. Later he join at IIT Kharagpur, India for the development of air-stable all inorganic perovskite solar cells using some atomic scale investigations. Now he joined at Łukasiewicz – PORT to develop two- and three-dimensional perovskite single crystals for optoelectronics application.
