  We experimentally demonstrate on-chip supercontinuum generation in the
visible region in angle etched diamond waveguides. We measure an output
spectrum spanning 670 nm to 920 nm in a 5mm long waveguide using 100 fs pulses
with 187 pJ of incident pulse energy. Our fabrication technique, combined with
diamonds broad transparency window, offers a potential route toward broadband
supercontinuum generation in the UV domain.
