Fabrication technology for specialty silica optical fiber using MCVD process
Anirban Dhar, Senior Scientist, Central Glass and Ceramic Research Institute (CSIR–CGCRI) (India)




A short piece of specialty optical fiber acts as the backbone of various fiber-based devices such as high-power laser, amplifier, sensor, etc. suitable for various applications like communication, medical diagnosis, industrial as well as advance basic research. The performance of this specialty optical fiber will depend on the selection of materials, fabrication process technology used, and suitable optimization of various process steps. Accordingly the fabrication of a good quality silica-based specialty fiber doped with suitable dopants in a reliable and repeatable manner is a key challenge from a technological viewpoint and will be briefly discussed.

Anirban Dhar is a senior scientist at CSIR–Central Glass and Ceramic Research Institute (CSIR–CGCRI), India, where he leads the specialty optical-fiber fabrication activity using MCVD–Chelate Delivery Technique. Prior to joining CSIR–CGCRI, he was a postdoctoral research fellow at the Institute of Photonics and Electronics of the Czech Academy of Sciences, Czech Republic, and at the Optoelectronics Research Center, University of Southampton, U.K.
Anirban’s research interests include the design, fabrication and optical/material characterization of various types of specialty optical fiber for fiber-based devices like fiber amplifiers, lasers and sensors.

Prospects for development of nanostructured free-form optical fibers
Ryszard Buczynski, Institute of Microelectronics and Photonics, and Univ. of Warsaw, Poland




Application of nanostructures for the development of optical fibers allows to shape their optical properties. Dispersion, modal and polarization properties of the nanostructured fibers are determined with internal discrete nanostructure of the core composed of multiple types of glasses. We discuss the current state of the art of this early-stage concept for silica and soft glass fibers, and their possible applications. Experimental verification and technological aspects of development of proof-of-concept nanostructured fibers are demonstrated.

Ryszard Buczynski received his PhD degree from Warsaw University of Technology, Institute of Physics and from Vrije Universiteit Brussel, Faculty of Applied Science, in 1999. He received DSc. in physics from University of Warsaw in 2012. He is a deputy leader of Institute board of Łukasiewicz Institute of Electronic Materials Technology and a professor of this Institute. He is an expert in the field of optical fibers, microstructure optics, nonlinear optics and optical technologies. His research interests include photonic crystal fibers, supercontinuum generation, microoptics, and microfluidics. His current research focuses on the development of nonlinear photonic crystal fibers based on soft glasses and nanostructured microoptical components. He is an author or co-author of more than 284 papers and several patents.
