Abstract

Mode-locked integrated mid-IR waveguide chip lasers with ultra-short pulse duration and high peak power are of great interest for a large range of applications like trace-gas spectroscopy and early-cancer detection. As those lasers are automatically embedded within a small block of doped glass, they are inherently robust and immune to environmental fluctuations. In this paper we investigate the suitability of various novel nanomaterials for the realisation of saturable absorbers for passive mode locking of femtosecond laser-written mid-infrared waveguide lasers. We compare and characterise saturable absorbers based on carbon nanotubes, graphene, topological insulators, transition metal dichalcogenides as well as black phosphorus and analyse their performance in a thulium-doped waveguide laser operating around 2 micron.
