BoxOptronics High Absorption Large Mode Field Erbium-ytterbium Co-doped Fiber has a unique core low NA design, which can achieve high beam quality output without reducing the pump conversion efficiency. The high cladding NA ensures high pump coupling efficiency, and the large core diameter design ensures a large mode field area and a short fiber length, thereby greatly reducing the threshold of nonlinear effects. The fiber has good consistency, better suppression of 1um parasitic ASE, high light-to-light conversion efficiency, and good stability under high-power operation.
Boxoptronics' 1.5um Passive Matching Fibers are matched with the erbium-ytterbium co-doped fiber, and the high matching performance reduces the splicing loss, ensuring the high-performance output of the erbium-ytterbium co-doped fiber in system applications.
Boxoptronics' 1.5um Polarization Maintaining Passive Matching Fibers are matched with the erbium- ytterbium polarization-maintaining fiber. The high matching performance reduces the splicing loss and ensures the high-performance output of the polarization-maintaining erbium-ytterbium fiber in system applications.
Boxoptronics' Germanium Doped Quad Core Passive Fibers are mainly matched with the four-core erbium-doped fiber, and the high matching reduces the splicing loss and ensures the high- performance output of the multi-core active fiber.
Boxoptronics' Highly Doped Phosphorus Raman Fibers are designed for efficient Raman lasers and amplifiers operating in the 1.1-1.6 µm spectral range. The main advantage of phosphorous-doped fiber is the three times higher Raman shift value compared to germanium-doped fiber. This feature can greatly simplify the design of Raman fiber lasers and amplifiers.
