Welcome to the XXI edition of the conference on Numerical Simulation of Optoelectronic devices

I am Paolo Bardella, the local chair of this conference. In agreement with the program chair Joachim Piprek and the steering committee, we decided to organize this edition as a virtual conference due to COVID 19 pandemic.

By registering on this site, you will have access to more than 80 video presentations, organized in 9 topics.

I thank all the authors from all over the world who decided to submit their most recent results to this conference in these complicated moments, and all the visitors from companies, research centers and universities.

I invite you to post comments and questions below the videos, to start an active interaction with the authors which is a fundamental aspect for the success of any conference.

I finally thank my colleagues from the micro- and opto- electronic group for their support and I wish you a great virtual conference.

Paolo Bardella
