doc. Ing. Václav Prajzler, Ph.D.

The Ph.D. thesis deals with the design and realization of photonic passive and active structures made from new polymer materials. Passive flexible polymer structures, such as optical splitters and, etc. will be designed and fabricated. Polymer layers doped with active ions for the realization of the optical amplifier will be also studied. http://www.micro.feld.cvut.cz/

In recent years, key advancements have been demonstrated in Power over Fiber systems and free space optical powering. The Ph.D. research study will be focused on the investigation of properties of different environments using optical fibers and free space that can be used to transmit optical energy and then convert the transmitted energy to electrical energy. At present, the limits of dielectric environments that could be used for the transmission of high optical energies for conversion to electrical energy and powering are not known in detail. The Ph.D. thesis is going to deal with studying the properties of high-power optical sources, optical fibers used for high-power transfers and photovoltaic converters. The aim of the work will be also to develop a model to describe the system for optical energy transmission and its conversion into electricity.

Preparation of optical polymer structures using new technologies such as 3D printing, laser lithography and etc. Their characterization, focusing mainly on the study of the waveguide properties.

The Ph.D. thesis deals with the study possibilities of optical fibers, optical sources, passive structures, optical power convertors and etc. using for applications in Power over Fiber (PoF) systems. The development of the PoF systems is a new scientific area that may benefit from their expected advantages such as galvanic isolation between two fiber ends, intrinsically safe nature, electromagnetic interference immunity and powering on-demand multiple sensors.

Preparation of optical materials doped with active ions and their characterization. The thesis solves the choice of optical materials suitable for active ions and the study of optical properties.

The thesis deals with a study of optical structures, which were made using new technologies as, e.g., 3D printing or laser beam writing. The properties of the real structures were analyzed by m-line spectroscopy and also by measurement of the surface plasmon resonance.

Study of properties of optical fiber waveguides, optical cables and planar optical waveguides, which could be exposed to the extreme environmental conditions, with a potential application in nuclear power plants.
