Integrated Component, Isolator and Single-Mode/Multimode WDM

This hybrid device combines an input multi-mode 9xx nm pump with a 1550 nm single-mode signal and a double cladding fiber (DCF) output for high-power optical amplification applications. A single-stage isolator for a 1550 nm signal is integrated into the device to allow better performance and greater integration of the high-power erbium doped fiber amplifier (EDFA) design.

This is a key component for cladding pumped high-power EDFAs. This device provides a flexible platform for interfaces with other specialty fibers, such as standard SMF-28 signal input fiber, low (0.15 NA) or high (0.46 NA) MM core NA independent to its core size on the 9xx nm input and output DCF ports.
