Efficient and robust second-harmonic generation in thin-film lithium niobate using modal phase matching
Mikkel T. Hansen, Emil Z. Ulsig, Fabien Labbe +4
A double-ridge waveguide is designed for efficient and robust second-harmonic generation (SHG) using the thin-film lithium-niobate-on-insulator (LNOI) platform. Perfect phase match…

Continuous-wave second-harmonic generation in the far-UVC pumped by a blue laser diode
Eric J. Stanton, Peter Tønning, Emil Z. Ulsig +6
Far-UVC light in the wavelength range of 200-230 nm has attracted renewed interest because of its safety for human exposure and effectiveness in inactivating pathogens. Here we pre…
