摘要
The third-order Kerr nonlinear response in gallium phosphide nanoscale waveguides is measured through continuous-wave (CW) four-wave mixing. The extracted nonlinear coefficient ranges from about 800 W−1 m−1 to 1400 W−1 m−1, consistently with an estimated material nonlinearity n2 3.5 × 10−18 W−1 m2. The roles of the residual absorption and the related thermal effects are discussed.
