About Jesper Mørk

Jesper Mørk is Professor, Group Leader and Head of the Nanophotonics Section at DTU Fotonik.

He is Center Leader of the newly inaugurated DNRF Center for Nanophotonics, NanoPhoton, at DTU. The center explores a new type of semiconductor nanocavity, which can concentrate light to extremely small dimensions, with important applications in lasers, quantum technology and the integration of electronics and photonics.

Jesper Mørk has been employed at DTU since 1996, first as an associate professor and since 2002 as a professor. He has been the research leader of several major international and national projects, including the Villum Center of Excellence, "NATEC", which recently finished after more than 10 years. Jesper Mørk is a Fellow of Optica (formerly known as the Optical Society of America) and has supervised more than 30 PhD students over time. In 2012, he was named PhD Supervisor of the Year at DTU.

Jesper Mørk receives the Order for his efforts as professor at DTU. 

It was sent by ordinary mail-order, the cross. But upon opening it, Jesper Mørk had the extraordinary experience of becoming a knight, sitting at his home office desk.

"I paused for a long moment. Then I opened the beautifully decorated box, revealing the cross of the Order of Dannebrog," Jesper Mørk remembers.

Jesper Mørk is professor at DTU Fotonik and center leader of NanoPhoton, the Center for Nanophotonics at DTU.   

Throughout his career, Professor Jesper Mørk has distinguished himself as one of the world's leading researchers in the field of light-matter interaction in semiconductors and laser dynamics.  

"I'm very honoured by this recognition, which I share with the many excellent and motivated colleagues and students I have had the good fortune of collaborating with over the years," says Jesper Mørk.

Among Jesper Mørk’s recent scientific contributions is the Fano laser. It is a new type of nanostructured laser, only one micron in size (one-thousandth of a millimetre), employing a resonance phenomenon known as a Fano resonance. Jesper Mørk and researchers in his group were the first in the world to suggest and experimentally demonstrate a Fano laser. When these results were published in Nature Photonics in 2017, it opened a new approach towards lasers.

And so, in 2019, to explore the physics and applications of this new class of photonic devices, Jesper Mørk received a EUR 2.5 million ERC Advanced Grant.

In August of this year, Jesper Mørk and his colleagues showed that the Fano laser has fundamental advantages compared to other types of lasers, in that the quantum noise can be reduced to very low levels. The results were published in Nature Photonics.

About the Order of Dannebrog.

Professor Jesper Mørk’s Order of the Dannebrog-cross,
Professor Jesper Mørk’s Order of Dannebrog-cross. 


According to the Royal House of Denmark, the Order of Dannebrog was established in 1671. But to make the new order more prestigious, a myth was maintained, that it was actually a re-establishment of a much older order. An order, which was told to be founded by the king Valdemar Sejr in connection with the crusade at Lyndanisse on 15 June 1219, where Dannebrog according to legend fell from the sky and secured the victory for the Danes. For the same reason, the sign of the Order has the shape of a cross, and Dannebrog's red and white colours characterize the ribbon and cross of the Order.

Originally, the order was limited to Danish princely and noble persons. But with the expansion of the Order of Dannebrog in 1808, the order was divided into several classes and the decorations were expanded to a much wider circle.
