Second harmonic generation in modal phase-matched AlGaAs-on-insulator waveguides
We utilize modal phase matching and type-I configuration to achieve second harmonic generation in AlGaAs-on-insulator waveguides. We demonstrate an overall normalized conversion efficiency of 200% W-1 cm-2 at a pump wavelength of 1587 nm in a 1-mm-long waveguide.
