## Contribution

The study introduces a novel fabrication technique for angle-etched diamond waveguides enabling broadband supercontinuum generation in the visible spectrum.

## Key findings

- Spectrum spans 670 nm to 920 nm
- Uses 100 fs pulses with 187 pJ energy
- Potential for UV supercontinuum generation

## Abstract

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.
