    Article Snippet: Hybrid optical fibers that integrate exotic materials within more traditional silica glass architectures open a route for the development of highly functional all-fiber photonic systems.. Here, a compact hybrid optical fiber platform is reported formed by depositing a silicon nitride (SiNx nitride-rich) nanolayer onto the surface of fused-silica microfibers via plasma-enhanced chemical vapor deposition.. The SiNx thickness can be precisely tuned over a range of tens of nanometers, while maintaining an ultra-smooth deposition surface, allowing for tunable coupling between the modes guided predominantly in the nanolayer and the fiber core.
