C-Band & L-Band Photosensitive Erbium-Doped Fiber
Nufern's high performance PS-ESF-3/125 is the ideal fiber for distributed feedback (DFB) and distributed Bragg reflector (DBR) lasers. Engineered to be inherently photosensitive, these fibers enable short device lengths and good pump conversion efficiency. Variants of this fiber with higher gain and/or photosensitivity are available upon request as custom products.
Geometrical & Mechanical Specifications
Coating Requirements: UV Cured, Dual Acrylate.
Other Requirements: Fiber designed to operate in the C-Band & L-Band.
Special Core Dopants: Erbium Doped, Photosensitive Fiber
Features & Benefits
- Inherently photosensitive with moderate Er dopant concentration—Enables short length devices with a superimposed fiber grating structure
- High efficiency—Good conversion of pump to signal power
- Perfectly matched passive fiber available—Facilitates the construction of fiber-based components and pigtails with low pump and signal coupling losses.
- Ultra-short very narrow linewidth all-optical DFB and DBR lasers
