Optical frequency combs for optical fiber communications by Leif Katsuo Oxenløwe

“…It is shown that currently, available comb sources can individually support multiple Pbit/s in short multiplexed links and also support ultra-long-haul reach with performance on par with using high-quality individual lasers. This means that, provided a number of practical solutions for matching and tuning combs, as well as replacing broken comb sources swiftly, are developed, amplified optical frequency combs could perform very well as replacements for banks of individual lasers in optical networks.…”

Non-Hermitian topology and entanglement in an optomechanical superlattice by Wojciech Brzezicki, Timo Hyart, Francesco Massel

“…The interplay between topology and dissipation can give rise to a wealth of new phenomena and pave the way for novel topological lasers, sensors, and other quantum devices. Along these lines, we propose here an optomechanical setup in which the concomitant presence of a spatially modulated external drive and dissipation gives rise to a topologically nontrivial state for mechanical and optical excitations. …”
