Four-wave-mixing in optical communication region has been successfully demonstrated by using the Ta2O5 based submicron channel waveguide. The geometrical dimension of Ta2O5 core is 700´400 nm2. The ultra-low propagation loss of 1.5 dB/cm in the Ta2O5 based channel waveguide enables the high power propagating in the core layer. Based on the continuous wave pump-probe measurement at pump/probe wavelengths of 1555.373/1556.08 nm, the converted signals of 1554.667/1556.787 nm via FWM processing in the Ta2O5 based channel waveguide are observed. The conversion efficiency of -49 dB is determined, and the calculated nonlinear refractive index is 1.5±0.6´10-14 cm2/W at ~1550 nm. Our primarily results indicate that the nonlinear optical property of Ta2O5 is comparable to Si3N4, and shows great potentials in the nonlinear waveguide applications.
