Dear Colleagues,
Dear Friends,

It is my honour and privilege to welcome you to the Sunrise Valley here in the lovely city of Vilnius for a historic milestone—the 20th APROPOS Conference.

We extend our deepest gratitude for your time, your brilliant insights, and your sincere efforts in contributing to this event. Your presence enables us to celebrate the beauty of physics, the elegance of optoelectronics, the charm of advanced nanostructures, and the fascinating phenomena that arise when optics meets electronics.

Since its inception in 1971 as a symposium on plasma and instabilities in semiconductors, this conference series has continually evolved. Over more than five decades, it has grown from “Ultrafast Phenomena in Semiconductors” into the modern APROPOS platform. Yet, throughout this journey, it has preserved its long-standing scientific traditions while pushing the boundaries of semiconductor research and industrial integration.

Nurturing the next generation remains a core pillar of our mission. Starting on September 29, the Tutorial Session, co-organized with the International Young Scientists’ Symposium, offers students and young researchers an extraordinary masterclass—a tradition successfully launched back in 2022. With sessions exploring heterogeneous integration, terahertz electronics, photonic integrated circuits, and near-field optical microscopy, we are proud to foster Baltic and international scientific synergy.

This year, the conference is enriched by the traditional Lublin Readings session on Wednesday, September 30. We are privileged to host special guest Dr. Darius Staliūnas from the Lithuanian Institute of History, who will lecture on “Vilnius in the 19th Century: Memory Politics, Symbolic Geography, and Competitive Claims to the 19th-Century City”. Following this deep dive into our regional identity, on Friday, October 2, we invite you to explore the city’s multicultural heritage further with a tour of the Central Vilnius University Ensemble and the Old Town.

We gather today in a complex and challenging world. In 2026, the realities of geopolitical uncertainty and regional strain remind us that peace, security, and international collaboration cannot be taken for granted. In times of division, science must serve as a universal bridge. Bringing together minds from across Europe, the UK, Taiwan, Japan, the United States, and beyond reinforces the fact that democratic unity and shared knowledge are our greatest values.

We are highly indebted to the Research Council of Lithuania, HERMES, and ChipsC² LT for making this event possible. Moreover, we extend our highest appreciation to our sponsors—attocube, EKSPLA, Light Conversion, TERAVIL, Terahertz Technologies, Barnas, and Monospektra—for sponsoring the tutorial session, the coffee breaks, and the establishment of the Researcher Awards.

I wish you a very productive week through illuminating conference tracks and enlightening debates as well as breakthrough ideas and encouraging discoveries that defy everyday routines. If APROPOS 2026 can spark a small step toward closer collaboration, we will be deeply fulfilled, knowing we have made a meaningful contribution to creating a more advanced, secure, and peaceful society.

Welcome to the 20th APROPOS Conference!

Vilnius, 30th September 2026
