Abstract

A tapered hybrid microfiber comprising a metal core and a glass silicate cladding is the platform proposed here for the development of plasmonic sensing devices. The existence of the glass cladding provides several advantages over pure metal tips while exhibiting high enhancement factors at the tip apex up to 104. Optimization of the fiber tapering process conditions can be achieved by using different metals having different melting points, viscosity and thermal expansion coefficients as well as composite fibers with different glass and metal core diameter in order to achieve tapered microwires with the desirable geometrical and operational characteristics.
