Nanophotonic Waveguide Supercontinuum
Octave-spanning bandwidths with low pulse energy
Supercontinuum generation allows a pulsed laser with narrow bandwidth to be broadened to many times its original bandwidth. Broad bandwidth is critical for many applications, including spectroscopy and self-referencing of frequency combs. Nanophotonic waveguides enable supercontinuum with significantly lower pulse energies than nonlinear fibers and provides excellent control over the shape of the output spectrum.
We offer fully connectorized nonlinear supercontinuum waveguides, providing simple plug-and-go usability. Our most popular version enables the efficient generation of 780 nm light from a 1560 nm mode-locked laser for low-power frequency comb stabilization. Pulse energies as low as 100 pJ (at <200 fs duration) can be used.
Our packaged tantala nonlinear waveguides achieve excellent coupling efficiency and are mechanically rugged. This technology opens new doors in precision timekeeping, quantum science, biological imaging, and remote sensing.
