A paper in APL Photonics, from AIP Publishing, provides a perspective of the field of ultra-wideband photonic waveguide platforms based on wide bandgap semiconductors. These waveguides and integrated circuits can realize power-efficient, compact solutions, and move key portions of ultra-high-performance systems to the chip scale instead of large tabletop instruments in a lab.

Until now, key components and subsystems for applications, such as atomic clocks, quantum communications and high-resolution spectroscopy, are constructed in racks and on tabletops. This has been necessary because they operate at wavelengths not accessible to silicon waveguides due to its lower bandgap and other absorption properties in the UV to near-IR that reduce the optical power handling capabilities, among other factors.
