Supercontinuum generation in angle-etched diamond waveguides.

Abstract

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