Abstract

The field of mid-infrared fiber photonics has seen significant progress in recent years [1]. In virtually all molecules, transitions involving changes in both vibrational and rotational states can be excited by illumination with light at midinfrared wavelengths from ~ 2 – 15 Μm, giving rise to a plethora of application in environmental sensing, defense, and medicine, to only name a few. However, for most applications, compact and monolithic laser sources without bulky and sensitive free-space optical components are needed. While in-fiber components in mid-infrared compatible soft-glass fibers [2,3] as well as fiber endcaps [4] for long-term stable operation have both been demonstrated, little work to date has focused on the fabrication of fiber-pigtailed optical chips that could offer additional functionalities. The femtosecond laser direct-write technique is a highly versatile method that enables the inscription of tailored three-dimensional photonic circuits into bulk glasses [5]. Here we summaries our recent progress into the fabrication of linear and nonlinear waveguide chips for the realization of all fiber mid-infrared sources.
