Home / Germanium-doped multimode optical fiber
Germanium dioxide serves as the primary dopant in optical fiber cores, where it modifies the silica glass matrix to raise the refractive index. With fiber production exceeding 600 million fiber-kilometers annually, germanium demand in this sector is expected to reach 80+ metric tons per year by 2026. For the fabrication of bend insensitive Fiber Bragg Grating (FBG) arrays, Fibercore offer three, high germania fibers: SM1500(4. The multimode (MM) fibers are available in Graded Index (GRIN) variants with 50μm and 62. A reconfigurable multiwavelength erbium-doped fiber laser based on an all-fiber multimode interferometer (MMI) is proposed and experimentally demonstrated.
A conventional silica fiber achieves single-mode guidance through a simple refractive index step: the germanium-doped core has a slightly higher index than the pure silica cladding, and total
