Supercontinuum.pl Research Group takes from over 30 years of experience in fiber optic technology and glass synthesis of the Department of Glass at Institute of Electronic Materials Technology in Warsaw, Poland. Designing technology of photonic crystal fibers has been investigated and developed in the Department for over a decade. Technological expertise of the Department is complemented by team from Information Optics Department at Faculty of Physics, University of Warsaw, with experience in area of design and spectroscopic characterization of optical properties of micro-optical elements.

As a result of many years of fruitful cooperation of the two teams, the Supercontinuum.pl Research Group was established, who presently realize project titled „Novel light sources based on photonic crystal fibers with nanostructured cores”, which is financed within the Foundation for Polish Science Team Programme, co-financed by the European Regional Development Fund, Operational Program Innovative Economy 2007-2013.

The aim of the Project is developing of new class of supercontinuum sources – broadband sources of coherent radiation – operating in spectral range covering wavelengths from the visible around 500 nm, up to mid-infrared around 5000 nm. Use of photonic crystal fibers made from multicomponent glasses, enables significantly larger degree of freedom in designing of dispersion properties.

Innovation of Project is within the use of nanostructure in the core area of photonic crystal fiber, which enables additional degree of freedom in designing a dispersion profile for given pump laser wavelength, which is unavailable for classic photonic crystal fibers. Use of new compositions of multicomponent glasses for photonic crystal fiber drawing in the Project is also innovative, since it opens up spectral range up to around 5000-6000 nm, while transmission of classic silica fibers is limited up to around 2400 nm. Glasses developed and synthesized in the Supercontinuum.pl Research Group feature also nonlinearities, which are an order of magnitude, up to two orders of magnitude higher, compared to silica glass. At the same time, material properties of our glasses allow for multiple thermal processing without recrystallization, which enables drawing of air-solid or all-solid (twin glass type) photonic crystal fibers.
