The device is a compact, highly-coherent dual-wavelength source, with high conversion efficiency up to 280%/Wphotonicsnonlinear opticssilicon nitrideself-injection lockingSelf-injection Locked Second-Harmonic Generation in Optically Poled Silicon Nitride Microresonatorstext::conference output::conference paper not in proceedings
