In May 2018, OSA hosted an Incubator Meeting, “Integrated Photonics in the Mid-IR,” that explored both practical applications of photonic-chip integration and the critical barriers currently preventing prototyping in the mid-infrared. This band of the spectrum, 3 to 5 microns, is a coveted wavelength range for spectroscopy and sensing of a variety of molecules, and for other applications. But integrated devices in the mid-IR have proved technically challenging to execute, highly specialized and expensive—factors that have held back moving to new applications.
