Mid-infrared semiconductor laser spectroscopy with hollow core fibers (Conference Presentation)
Author(s): Wei Ren

Paper Abstract

There is a trend for the development of mid-infrared laser spectroscopy with remote interrogation, multiplexed multi-point detection, and integrated photonics systems. The merging of semiconductor lasers with hollow-core fibers is one of the promising strategies for these purposes. In this talk I will discuss recent progress on mid-infrared laser spectroscopy performed in a novel type of hollow-core negative curvature fiber (HC-NCF). Sensitive CO, N2O, and H2CO detection between 2.3 and 3.6 µm using absorption spectroscopy will be presented. Photothermal sensing in the HC-NCF will also be discussed using the mid-infrared-pump and near-infrared-probe scheme recently proposed by our group.
