Seeded Multimode Quasi-Phase-Matching in All-Optically Poled Silicon Nitride Waveguides
2021
CLEO: Applications and Technology in Proceedings Conference on Lasers and Electro-Optics
We demonstrate seeding-enabled all-optical poling of silicon nitride waveguides as short as 5 mm, and account for quasi-phase-matching (QPM) inside the waveguide between the fundamental mode of pump and higher order second-harmonic modes.
