ITEE-DP: Foundations of waveguide and integrated optics

Monday, December 12, 2016 to Friday, December 16, 2016

 

Infotech Oulu Doctoral Program

CAS RU organizes a post-graduate course on Optoelectronics during 12th of Dec – 16th of Dec 2016. The topic of the course is “Foundations of waveguide and integrated optics”.

The lectures will be given by Dr. Eugene Avrutin from the University of York, UK. The lectures will be given during 9am and 1pm during 5 days. The seminar classes, detailed timing and credit units will be given later.

Those willing to participate, please register by an email to Juha Kostamovaara (juha.kostamovaara(at)oulu.fi) by the 2nd of Dec.
