Wafer-scale inverted gallium phosphide-on-insulator rib waveguides for nonlinear photonics
We report a gallium phosphide-on-insulator (GaP-OI) photonic platform fabricated by an intermediate-layer bonding process aiming to increase the manufacture scalability in a low-cost manner. This is enabled by the “etch-n-transfer” sequence, which results in inverted rib waveguide structures. The shallow-etched 1.8 µm-wide waveguide has a propagation loss of 23.5 dB/cm at 1550 nm wavelength. Supercontinuum generation based on the self-phase modulation effect is observed when the waveguides are pumped by femtosecond pulses. The nonlinear refractive index of GaP, n, is extracted to be 1.9 × 10 m/W, demonstrating the great promise of the GaP-OI platform in third-order nonlinear applications.
