Open days for business

 The aim of the open days for business at the Faculty of Physics is to inform industry about the scientific capabilities of the Faculty, the results of undertook research and technological solutions developed at the Faculty. We also learn what are the expectations of the industry in relation to the research topics, and which research would be welcomed the most by the business partners. Several open days for business have been organised since the end of 2014:

- on the 21st of October 2014, a meeting was organised with the representatives of Astri Polska Sp. z o. o. represented by Aneta Michałkiewicz and Jerzy Krężel. http://astripolska.pl/

- on the 13 Jan 2015, a meeting was organised with the representatives of Saule Technologies. Olga Malinkiewicz from Saule Technologies Sp. z o.o. was our guest. http://sauletech.com/pl/

- on the 12 May 2015, a meeting was organised with the representatives of InPhOTech - Tomasz Nasiłowski and Marek Napierała http://www.inphotech.pl

- on the 18 June 2015, a meeting was organised with the representatives of Kubara Lamina S.A - Mariusz Błażejewicz and Dariusz Baczewski.  http://www.kubara-lamina.com/pl/start

 

 

 

Patent application for a broadband tunable FP

The patent application P.413956 for a broadband, tunable, Fabry-Perot interferometer, invented by Wojciech Wasilewski and Jarosław Iwaszkiewicz has been submitted to the Polish Patenting Office on 14.09.2015 r.

Application summary:

The subject of this invention is a broadband tunable Fabry-Perot interferometer, which includes two parallel semi-transparent mirrors (1), positioned inside a metallic tube (2), characteristic by means of that the tube (2) is supported with a heat source and a source of static magnetic field (9), while inside the tube (2) are located two surrounding ridges (8), which are supporting the mirrors (1) positioned inside the tube (2), with the mirrors (1) precisely attached to the ridges (8).

Patent application for focal distance measurement

A patent application P.412267 for the measurement of the position of the focal plane and focal distance of an optical set-up (Pol. "Układ pomiarowy do wyznaczania położenia płaszczyzny ogniskowej i długości ogniskowej układu optycznego oraz sposób wyznaczania położenia płaszczyzny ogniskowej i długości ogniskowej układu optycznego") has been submitted to the Polish Patenting Office on 08.05.2015 r. The application is authored by Wojciech  Wasilewski and Radosław Chrapkiewicz.

Summary of the application:

The invention includes a measurement set-up for the determination of the position of the focal plane and for the measurement of the focal distance of an optical set-up, which comprises, located at the optical axis (4), a light source (1), a movable detector (5), and at least two similar diffraction gratings (2,3) positioned in between the light source (1) and the optical set-up (4). The invention includes the method for the determination of the focal plane location and for the measurement of the focal distance of an optical set-up, in which the optical set-up (4), is being positioned in between the diffraction gratings (2,3) and the detector (5). Following, at least one of the diffraction gratings (2,3) is rotated along the axis of the set-up to reach a non-zero angle in between the diffraction gratings as well as the position of the detector (5) is varied along the optical axis, until the focal plane is found, at which the spots at the detector (5) will overlap.

 

 

Patent application for a microoptical device

The patent application P.413667 entitled "Microoptical device" has been submitted to the Polish Patenting Office on 28.08.2015 r. The inventor of the patent application is Andrzej Kaźmierczak.

Application summary:

The invention consists of a microoptical device for coupling of optical signals. The device is composed of a uniform host element that includes two matrices of lenses positioned at its different edges and of at least one mirror. Two lenses belonging to different matrices are functionally matched with at least one mirror from the mirror matrix positioned inside the host element.

Workshop on ultrafast science and femtochemistry

The workshop on ultrafast spectroscopy and femtochemistry organized within the framework of the PhoQuS@UW project at the Faculty of Physics UW (FPUW) took place on 29-30.09.2015. The goal of the workshop was to design experiments, test new ideas and plan the new research carried out in the laboratories of the Division of Optics FPUW, which have just been moved to the new building of the Faculty of Physics. Using the opportunity given by the PhoQuS@UW project the experimental setups in the laboratories will be rebuilt to improve them taking into account current frontiers and most interesting topics of ultrafast optical spectroscopy and femtochemistry. During the workshop we hosted four world renowned specialists in the field : Philipp Kukura, Marcus Motzkus, Arnulf Rosspeintner and Eric Vauthey. Under the supervision of the specialists we learned various schemes of ultrafast time-resolved spectroscopy such as frequency upconversion fluorescence spectroscopy, stimulated Raman spectroscopy, microspectroscopy with shaped laser pulses and infrared transient absorption spectroscopy. We also designed several schemes of coherent control experiments which can be used to control the double hydrogen transfer process in organic molecules belonging to the family of porphycenes currently studied in the Division of Optics. New ideas, the knowledge and know-how shared by the specialists could be verified in practice and consolidated during practical exercises carried out in the laboratories (making use of numerous optical materials).
