Mid-IR supercontinuum generation in chalcogenide fibers for applications in the molecular fingerprint region
The mid-infrared spectral region is of great interest because most molecules display fundamental vibrational absorptions herein, leaving distinctive spectral fingerprints for applications in e.g. spectroscopy, fluorescence microscopy, optical coherence tomography and hyper-spectral imaging. However, many mid-infrared sources are limited either in brightness, wavelength range or coherence, such as thermal emitters, or inconvenient and bulky, such as synchrotron sources. In this presentation we discuss the development of mid-infrared supercontinuum sources based on chalcogenide fibers, which have recently been demonstrated to cover a wide wavelength range from 1.4 μm to 13.3 μm in just 8 cm of fiber. Development of a compact mid-infrared chalcogenide fiber-based supercontinuum source will have key importance for applications such as early detection of skin cancer, gas sensing and food quality control.
