Stimulated Brillouin Scattering of Higher-Order Acoustic Modes in Four-Core Tellurite Microstructured Optical Fiber

In this paper, we present a new way of enhancing the Stimulated Brillouin scattering (SBS) of higher-order acoustic modes in the four-core tellurite (TZLB) microstructured optical fiber (MOF). The Brillouin gain spectrum (BGS) in the MOF is calculated based on a full model analysis of the optical an...

Description
Summary:In this paper, we present a new way of enhancing the Stimulated Brillouin scattering (SBS) of higher-order acoustic modes in the four-core tellurite (TZLB) microstructured optical fiber (MOF). The Brillouin gain spectrum (BGS) in the MOF is calculated based on a full model analysis of the optical and acoustic properties. In contradict to the single-core tellurite MOF, BGS of the four-core tellurite MOF has three peaks, which are contributed by the fundamental and higher-order acoustic modes. The higher-order acoustic modes can enhance the interaction with the optical mode and provide a strong contribution to the Brillouin response.
