This paper is a research survey of WILGA Symposium work, 2010-2012 Editions, concerned with Optical Fibers, Optoelectronic Devices, Sensors, Communication and Photonics Applications. It presents a digest of chosen technical work results shown by young researchers from different technical universities from this country during the three recent Wilga Symposia on Photonics and Web Engineering. Topical tracks of the symposia embraced, among others, nanomaterials and nanotechnologies for photonics, sensory and nonlinear optical fibers, object oriented design of hardware, photonic metrology, optoelectronics and photonics applications, photonics-electronics co-design, optoelectronic and electronic systems for astronomy and high energy physics experiments, photonic equipment for JET tokamak and pi-of-the sky experiments development. The symposium is an annual summary in the development of numerable Ph.D. theses carried out in this country in the area of advanced electronic and photonic systems. It is also a great occasion for SPIE, IEEE, OSA and PSP students to meet together in a large group spanning the whole country with guests from this part of Europe. A digest of Wilga references is presented [1-274]. Wilga Symposia play a role of an universal integrator of young science in photonics and related areas in this country and also in this part of Europe. More than 5000 young scientists participated in scientific Wilga meetings and discussions during the last nearly two decades. Over 2500 papers were published, including over 1000 in Proc. SPIE.
