Joint spectral characterization of SPDC photon pairs near 2 m in (Al)GaAs-on-insulator waveguides
Alexandre Z. Leger, Emil Z. Ulsig, Samuel E. Fontaine +8
Integrated photon-pair sources are a core component of chip-based quantum computing, communication, and metrology. Although such sources have been demonstrated at conventional tele…
Far-UVC Field Emission Device at 226 nm and its Sub-Nanometer thick GaN/AlN Quantum Well Anode
D. L. Boiko, P. Demolon, J. -F. Carlin +10
We report on unique features of ultra-thin GaN/AlN quantum wells and demonstrate a new field emission device for human-safe disinfection with an external quantum efficiency of 18%…
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…
