Description

Abstract
Project Objectives: - Study of fundamental properties of semiconductor materials of CuGa(In)S(Se)2, Cu2ZnAB4 (where A~Si, Ge, Sn; B~S, Se) and TlGa(In)S(Se)2 type and determination of fundamental parameters by studying polariton excitons and electronic transitions, natural and induced birefringence, gyration and spatial dispersion at different temperatures. - Study of semiconductor structures (InGaAsP, AlGaAs) used for manufacturing optic radiation emitters, photoreceivers and optic filters with ultra narrow bands. - Study of laser diodes, including VCSEL type, photodiodes, optic amplifiers, splitters, microlenses, multiplexers and demultiplexers for fiber optic communication systems and determination of optimal exploitation regimes in different optoelectronic systems. - Elaboration and manufacturing of devices and systems based on micro-optoelectronic devices with different applications in national economy (communications, medicine, environmental monitoring, mini-energetics, agriculture, etc.). - Elaboration of technologies and methods for monitoring and guiding the above mentioned optoelectronic systems in order to improve the functionality and reliability. - Training of young specialists by involving young engineers, PhDs, students and master degree students into research activities. - Implementation of obtained results into national economy. The relevance is to develop local micro-optoelectronics by: obtaining new knowledge and skills; modern studies of materials and devices in collaboration with partners from Romania, Switzerland, Ukraine; elaboration of new micro-optoelectronic devices for advanced applications; training of high qualification engineers. Usage methods: l-modulated optic spectroscopy of reflection, absorption, luminescence and birefringence; resonant Raman scattering; usage of advanced micro-controllers for manufacturing command and control modules. Expected results: determination of parameters and fundamental characteristics of semiconductor materials and publication of obtained results in journals with impact factor; elaboration and manufacturing of optoelectronic modules and systems and presentation of the obtained devices at inventions and technology transfer salons; implementation of obtained results into real economy sector and teaching process.
