Tellurite glass fibers for mid-infrared nonlinear applications

Abstract

In this chapter, we review recent progress of using tellurite glass nonlinear optical fibers for mid-infrared nonlinear applications. First, we introduce various fabrication approaches producing conventional solid core/cladding tellurite glass preforms and structured tellurite glass preforms. Second, two technical difficulties have been found during the early stage of using small-core tellurite glass fiber for generating nonlinear supercontinuum into mid-infrared region. Approaches such as glass dehydration and large-mode-area fiber have been developed for solving these problems.
