Strengthening innovation capacity

Strengthening innovation capacity at the Faculty of Physic, Warsaw University (FPUW) is one of the PhoQuS@UW objectives. The rationale behind such an approach is the match between EU’s priorities and FPUW’s potential. Innovation is widely believed to become the vehicle for future economic growth. Therefore it has been placed at the heart of the EU 2020 strategy with Innovation Union as one of its 7 flagship initiatives. On the other hand, FPUW being a strong research facility (ranked as 151-200 at the Academic Ranking of World Universities in Physics 2012 ) has a high potential for innovation. It is especially true in the research areas covered by PhoQuS@UW, namely photonic sciences, since they constitute the background of so many modern-day inventions. Within PhoQuS, the subject of innovation is run by a dedicated full-time innovation manager dr Cezary Samojłowicz and the Innovation Committee. e-mail: cezary.samojlowicz@fuw.edu.pl

First meeting of the Innovation Committee

The first meeting of the Innovation Committee took place on 21st of November 2013 at the University of Warsaw (Faculty of Physics). The meeting was attended by the following members of the Innovation Committee: - Dr. Marek Daszkiewicz – Director of the Maksymilian Pluta Institute of Applied Optics (INOS) and Coordinator of the OPTOKLASTER Mazovian Photonic Technology Cluster linking industry and academia with 24 industry and academic members. (http://www.optoklaster.pl/eng/members.htm) - Dr. Cezary Samojłowicz (IFD UW) – PhoQuS Innovation Manager - Dr. hab. Piotr Wasylczyk – Task 4.1 Leader - Prof. Tomasz Szoplik – WP4 Leader - Dr. Jakub Włodarczyk – group leader in innovative biomedical imaging technologies at the Nencki Institute of Experimental Biology, Polish Academy of Sciences – involved in the coordination of the Polish National Road Map for Research Infrastructures in Biomedical Imaging and partner in Euro‐BioImaging  – a large‐scale pan‐European research infrastructure project on the European Strategy Forum on Research Infrastructures (ESFRI) Roadmap (www.eurobioimaging.eu). - Dr. Katarzyna Kołacz (INOS) – secretary of the OPTOKLASTER Mazovian Photonic Technology Cluster. - Dr. Marcin Szumowski – Entrepreneur and business development manager for the Bio-Tech-Med Cluster Mazovia (www.btm-mazovia.pl) did not attend the meeting due to his temporal stay at Stanford University, where he is currently attending ”Top 500 Innovators” programme organized by Ministry of Science and Higher Education. During two hours meeting discussion covered emerging new law regulations, European projects progress, scientific issues and possible areas for collaboration. Also a decision about the date and place of the scientific workshop has been taken.

Patent application filled on a novel colour filter

Four inventors : Michał Nawrot, Łukasz Zinkiewicz, Bartłomiej Włodarczyk, and Piotr Wasylczyk; have filled and submitted a patent application to the Polish Patent Office. Polish patent application number P.406178 entilted "Transmisyjny optyczny filtr barwny oraz sposób jego wytwarzania" was filled on 21st of November 2013. A paper based on the present invention has been published on the 30th of December 2013: "Transmission phase gratings fabricated with direct laser writing as color filters in the visible", OPTICS EXPRESS 2013, 21 (26), 31919-31924, DOI:10.1364/OE.21.031919. Publication abstract: “Simple diffraction structures having the form of a regular grid of pillars can generate a significant range of hues in white light transmission due to color-dependent diffraction into higher orders. We present the fabrication of such submicrometer scale structures by three dimensional laser two-photon photolithography, results of their optical properties measurements and compare the latter with numerical simulations.”

Research highlights at the Faculty of Physics - a workshop addressed to representatives of business and industry

Scientific workshop presenting the research highlights at the Faculty of Physics. The workshop was organised on the 30th of January 2014 in the new building of the Center for Novel Technologies III of the University of Warsaw (Żwirki i Wigury 101 street). Its purpose was to present the research highlights at the Faculty of Physics UW to representatives of business and industry and to encourage the development of links and to help to determine potential domains for collaboration between industry and the Faculty of Physics. Around 40 participants took part in this event. The program consisted of four presentations (20 min talks + 10min for open discussion) followed by informal meetings during coffee breaks and lunch. Talks were given in Polish by: - Dr Tomasz Stefaniuk („Nanolayers for plasmonics”), - Dr hab. Piotr Wasylczyk („Fast prototyping in microscale – 3D 2-photon photolithography”), - Dr hab. Yuriy Stepanenko („High power lasers”), - Dr Rafał Demkowicz Dobrzański („Quantum metrology”),

Microoptics and photonics group

The research interests of Microoptics and Photonics Group cover nanostructured gradient index components based on the effective medium theory, optofluidic devices, mid-infrared transmitting optical fibers and optical components, and nonlinear fiber optics. One of the main focus points of current research in nonlinear fiber optics is supercontinuum generation. Efforts are aimed at developing of a 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 and advantage of the Microoptics and Photonics Group in this area is within the use of nanostructure in the core of photonic crystal fibers, which enables yet an additional degree of freedom in designing a dispersion profile for the given pump laser wavelength. Use of new compositions of multicomponent glasses for photonic crystal fiber drawing is also innovative, since it opens up the 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-house at the Glass Department of Institute of Electronic Materials Technology feature also high nonlinearities, which are an order or two orders of magnitude higher, as those silica or fluoride glasses. 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. The group also study optical properties of a nanostructured microoptical components with various optical functionalities as axicons, multiple focus lenses or birefringent materials. Axicon structures are devoted to generation of focus line along optical, axis as well as multiple focuses, due to combination of axicon and diffractive optical elements within a single nanostructured element. This approach is based on the Maxwell-Garnett effective medium theory, and allows designing all-dielectric structures with arbitrary topological distribution in 2D and multiplied along the 3rd dimension. Developed multifocus components can be used for construction of an 3D array of optical traps for small particles in solvent. The scope of the research covers both experimental and theoretical study of nanostructured multifocus axicon components.
