%X Gallium nitride (GaN) is a promising material for nonlinear optics. It offers a second-order nonlinearity up to 20 pm/V and a third-order nonlinearity that is one order of magnitude higher than in silicon nitride at 1550 nm [1], [2]. Owing to its large bandgap of 3.4 eV GaN has a wide transparency range and is free of two-photon and three-photon absorption in the technologically important erbium-gain window. Recent advances have explored integrated GaN waveguide as a new platform for integrated photonics, demonstrating second-harmonic generation, four-wave mixing, soliton generation [2]–[4], supercontinuum generation and chip-based f-2f interferometry [5].
