Photonic integration platform for rubidium sensors and beyond

We have advanced the heterogeneous silicon nitride photonic platform, enabling operation at the 780 nm wavelength range for rubidium sensors and other applications while remaining operable at high temperatures up to 110 ∘ C. This platform surpasses other existing technologies with the superior integration of a comprehensive set of active building-block devices to enable fully integrated high-performance systems-on-a-chip.
