The Royal Academy of Sciences and Letters

The Royal Academy of Sciences and Letters has existed since 1742, and has about 250 national and 250 international members. Former members include H.C. Ørsted, Niels Bohr, Bengt Strömgren, Charles Darwin, Albert Einstein, Marie Curie and more. The Royal Academy has since 1899 resided with the Carlsberg Foundation in H.C. Andersens Boulevard 35 in central Copenhagen.

In an announcement on May 17 2022, the Royal Academy announced its inclusion of 15 new members in the natural sciences class. Professor Oxenløwe was among them, and he was elected, based on his continued efforts in an applied science field that requires fundamental new insights from a broad range of topics from basic information theory, linear and nonlinear optics, materials science, device physics, integrated photonics and quantum communication.

With professor Oxenløwes DNRF centre of excellence, SPOC (Silicon Photonics for Optical Communications), he is on a quest to find solutions to the major societal challenge of our communication infrastructure – the extreme energy consumption of the internet, and the continuous need for more capacity to enable climate-saving digitalisation actions. Here, being an engineer by training (PhD) and a physicist by heart (MSc) has given him good tools and perspectives to explore novel methods and technologies to develop high-capacity optical communication systems that show both high energy-efficiency as well as high spectral-efficiency. His work includes several world records and award-winning demonstrations, such as demonstrating that a single photonic chip-based frequency comb source can create enough light to carry more than the total worldwide internet traffic, and that nonlinear optical effects have the powers to increase signal processing speeds with orders of magnitude, compared to its electrical counterparts, and have orders of magnitude higher spectral and processing bandwidths.

Professor Oxenløwe hopes to use his seat in the highly esteemed Royal Academy to create more awareness of science, and engage in many cross-disciplinary discussions with other scientists to learn more about the great challenges of our time.
