This mid-IR PIC platform readily extends to longer wavelengths and opens the door to applications from distributed gas sensing and portable dual comb spectroscopy to weather-resilient free space optic

The current mid-infrared photonic integrated circuit (PIC) platform has the potential to be expanded to longer wavelengths, thereby enabling an array of applications such as distributed gas sensing, portable dual comb spectroscopy, and weather-resistant free space optical communications. This extension would offer an opportunity to enhance the existing PIC platform and expand its functionality, thus making it more versatile and applicable in a range of scientific and technological fields.
