Long distance transmission through distributed erbium-doped fibers

Fundamental Design of a Distributed Erbium-Doped Fiber Amplifier for Long-Distance Transmission

Long distance transmission in few-mode fibers.

Using multimode fibers for long-haul transmission is proposed and demonstrated experimentally. In particular few-mode fibers (FMFs) are demonstrated as a good compromise since they are sufficiently resistant to mode coupling compared to standard multimode fibers but they still can have large core diameters compared to single-mode fibers. As a result these fibers can have significantly less nonl...

Hybrid Raman/Erbium-Doped Fiber Amplifiers for WDM Transmission Systems

As light pulses propagate along the optical fiber, their energy dissipates. Beyond a certain distance the number of photons in pulses becomes too small to be detected. The optical pulses in fibers are energized by utilizing optical fiber amplifiers. The rapid growth of the internet and data traffic in optical fiber communication networks has stimulated the study of wideband optical amplifiers. ...

CMOS Compatible High Power Erbium Doped Distributed Feedback Lasers

On chip, high power (75mW), erbium-doped distributed feedback lasers are demonstrated in a CMOS compatible fabrication flow. The laser cavities consist of silicon nitride waveguide and grating features defined by wafer-scale immersion lithography and a top erbiumdoped aluminum oxide layer deposited as the final step in the fabrication process. 2013 Optical Society of America OCIS codes: (130.0...
