文摘We introduce a nanoscale photonic platform based on gallium phosphide. Owing to the favorable material properties, peak power intensity levels of 50 GW∕cm^2 are safely reached in a suspended membrane. Consequently,the field enhancement is exploited to a far greater extent to achieve efficient and strong light–matter interaction.As an example, parametric interactions are shown to reach a deeply nonlinear regime, revealing cascaded fourwave mixing leading to comb generation and high-order soliton dynamics.
