Abstract
We review the technologies of fiber fusion and fused device fabrication for fiber sensing applications. Fiber interconnection and fused fiber components are integral parts in optical fiber sensing modules and systems. Dissimilar fibers need to be fused together with low loss and high strength to ensure long-term performance stability. Fused fiber components, such as fused couplers and polarization-maintaining (PM) components, are important for both coherent and incoherent detection. In addition, the latest advances in nano/micro-fiber device and multi-port signal combiners pose new challenges to the fiber fusion and fused component technologies. We describe fundamental optics, discuss fabrication techniques for these devices, and present some application examples.
