Abstract

Near 2.5-octave supercontinuum (SC) generation spanning from 0.5 to 2.9 μm is reported in a well dispersion-engineered Ta₂O₅ waveguide pumped by a dual-wavelength femtosecond fiber laser at 1.55 μm and 1.97 μm, respectively, which is the broadest spectrum reported so far in Ta₂O₅ material platform. Moreover, there are no residual pump components in the spectrum, and the pulse energy conversion efficiency shows a record level of around 92%. Additionally, the fluctuation of the output power stability is within 0.33% over an hour. The results demonstrate the enormous potential applications of the Ta₂O₅ waveguides in nonlinear integrated photonics.
