            **Tantala waveguide devices for supercontinuum generation**. a) We fabricate waveguide devices of tantala material with silica cladding for supercontinuum generation with an input modelocked laser pulse source. By varying the geometry of the waveguide, we control the supercontinuum generation process. (b) Our integrated photonics platforms support low loss advanced packaging to optical fiber. (c) Demonstration of extended device operation in the packaged format. (d) Supercontinuum generation optimzed for frequency comb self-referencing in which nonlinear generation at the second harmonic of the 1560 nm input laser, hence 780 nm, supports efficient carrier-envelope offset frequency detection for ultraprecise optical metrology.
