Opis:: SPIE - PSP WILGA Symposium gathers two times a year in January and in May new adepts of advanced photonic and electronic systems. The event is oriented on components and applications. WILGA Symposium on Photonics and Web Engineering is well known on the web for its devotion to "young research" promotion under the eminent sponsorship of international engineering associations like SPIE and IEEE. WILGA is supported by the most important national organizations like KEiT PAN and PSP-Photonics Society of Poland. The Symposium is organized since 1998 twice a year. It has gathered over 4000 young researchers and published over 2000 papers mainly internationally, including more than 1000 in 10 published so far volumes of Proc. SPIE. This paper is a digest of WILGA Symposium Series and WILGA 2010 summary.

Opis:: Light plays a key role in human’s life. Without light there will be no human life environment. Technologies based on light, called photonics, decide of the development of our civilization. The role of photonics is constantly increasing, especially in such fields as energy, education, agriculture and health. The UN has established the International Year of Light and Light - based Technologies – IYL2015 [1]. The organizers of IYL2015 events are professional organizations, communities, educational organizations, non-profit ones, technological clusters and platforms, but also private sector. The aim is to increase the social consciousness about the role of light and photonics in building of our civilization. This sort of recognition is necessary as a needed component of the development process of the society. Introduction of new technologies, like completely new kind of lighting, new diagnostic and therapeutic methods, new sources of energy, etc., must meet with social acceptance. In the opposite case, isolated development of infrastructure, will meet with obstacles. In Poland, the professional events, technical, trade fairs and outreach ones, are organized in the framework of the IYL2015 by Photonics Society of Poland, Polish Physical Society, Polish Platform of Photonics Technologies, etc. The paper summarizes the issues combined with the organization of the IYL2015 globally and in Poland. Extended version of this paper was published in Polish [2]. The paper is a part of a cycle of articles devoted to analysis of global processes of photonics development. Previous papers concerned initiatives Photonics21 in Europe [3-4], NPI – National Photonics Initiative in USA [5], and development of optical sciences in Poland [6-15].

Opis:: This paper describes methods to extract nominal values of propagation quantities for thin-film, straight interconnect elements. The propagation quantities like effective dielectric permittivity ɛ_eff, attenuation α, characteristic impedance Z_o are calculated with the use of analytical and approximated formulas. These expressions are obtained by transforming and by fitting formulas, typically used for calculation of per unit length transmission line parameters. Methods are verified for typical thin-film interconnect elements dimensions and for typical materials used in the Photonics Integrated Circuits (PIC). The novelty of the study is the parametrization with respect to the geometrical dimensions. The parametrization is based on the approximation expressions in the form of rational polynomials obtained by fitting.

Opis:: In this work, the authors propose the design of an electro-optical silicon-photonics hitless switch that follows wavelength-division multiplexing (WDM) conditions in terms of channel bandwidth, shape factor, and free spectral range. Through a careful step-by-step design, the authors study a switch device composed of a coupled-resonator optical waveguide (CROW) structure merged with a Mach-Zehnder interferometer (MZI) modulator. The MZI modulator controls the coupling to the CROW and hence turns the switch on and off. The traditional matrix analysis of the CROW structure is modified to accommodate the MZI modulator section. The proposed switch requires a chip area of less than 0.01225 mm². The switch transmission satisfies WDM requirements with a channel-free spectral range of 100 GHz, channel flat-top response with a passband for the through/drop ports of 64.6 GHz/33 GHz, and a shape factor of 0.76/0.6. Besides, the switch transmission features an insertion loss for the through/drop ports of 0.23/1 dB, a switching speed of 100 GHz, and a competitive switch-on/off ratio of 33 dB.

Opis:: The phosphosilicate for planar waveguides fabrication by using sol-gel, and particularly erbium-doped waveguide amplifiers, is reviewed. In particular, efforts to use sol-gel to improve molecular homogeneity in Er-doped phosphosilicate-based monolith and thin films will be discussed. A variety of material studies was carried out to investigate and optimize the sample preparation condition for such application. These include X-ray diffraction, the Fourier transform infrared and optical transmittance, absorption and refractive index calculation. The erbium nitrate precursors use is shown to alter the Er³⁺ ions doping in the prepared samples thermally treated in the final monolith glass form, in comparison to the use of thin film phosphosilicate sol-gel sample. Excess heat treatment is used to force prepared samples crystallization, moreover resulting photoluminescence analysis is used to detect the co-operative-up-conversion sample properties before and after heating.
