Description:
In the field of polymer planar waveguide optical amplifying and laser structures, there has recently been an upsurge in the research of new types of optical polymer materials based on dopants of optically active ionts Bi, Ce, Dy. The task is, through measurements of transmission optical spectral and power characteristics of selected samples, to design, implement and demonstrate new optical photoluminescent performances of the polymer materials fabricated in the collaboration with the University of Chemistry and Technology (VŠCHT). http://www.micro.feld.cvut.cz/

Description:
The design of a hybrid microoptical WDM transceiver and subsequent measurements of its receiving and transmitting part that has been created as an independent hybrid optoelectonical integrated circuit of the WDM transmitter and receiver. A component of microoptics will be used for both hybrid integrated components. Further aim of this paper is to design a planar solution of both above mentioned circuits with the use of optical polymer waveguide and other selected components of planar integrated photonics. http://www.micro.feld.cvut.cz/

- Department: Department of Microelectronics
-
Description:
In the field of optical amplification structures, progress has recently been made in the research of new types of optical active broadband materials based on lanthanoid ions and heavy metal activators. - Study the recommended literature and formulate a mathematical model to calculate the differential gain of the measured materials [ 1 ]. - Measure the reflection, transmission spectra and optical differential gain of new broadband materials for optical radiation amplifiers in the C, L and U spectral bands [ 2 ]. - In cooperation with the University of Chemistry and Technology (VŠCHT) and using a mathematical model, optimize their composition of materials to achieve maximum differential gain in selected spectral bands.
