An phase-sensitive amplifier (PSA) is capable of low-noise optical amplification. A frequency non-degenerate PSA (ND-PSA) requires idler light co-propagating with signal light. Therefore, spectral efficiency reduced by at least half compared to the system using phase-in-sensitive amplifiers such as an erbium-doped fiber amplifier. In this letter, we propose and demonstrate inter-band amplificat...
This paper seeks to understand the performance of an optical link in DWDM systems, with emphasis on the influence of Optical Amplifiers EDFAs and its characteristic parameters on the signal performance. We begin by studying the optical fiber transmission DWDM system, its various elements and its characteristic parameters. Then, for a specific optical fiber transmission DWDM system with specific...
We experimentally validate a black box model for long-wavelength erbium doped fiber amplifiers. The agreement between the model and the experiments is closer than in the case of conventionalwavelength erbium amplifiers. Introduction Several models have been proposed to predict gain spectral changes of Erbium Doped Fiber Amplifiers (EDFA) under different saturation conditions [1-3]. Most of thes...
A 10.5 Tbit/s optical transmission (15 x 100 Gbit/s QPSK channels per core) over 2,520 km of multicore fiber is achieved using an integrated multicore transmission link consisting of directly spliced multicore components such as fan-in/fanout fiber couplers, a 60 km trench-assisted 7-core hexagonal fiber and cladding-pumped erbium-ytterbium-doped fiber amplifiers.
Rhodamine 6G and Rhodamine B dye mixture doped polymer optical fiber amplifier (POFA), which can operate in a broad wavelength region (60 nm), has been successfully fabricated and tested. Tunable operation of the amplifier over a broad wavelength region is achieved by mixing different ratios of the dyes. The dye doped POFA is pumped axially using 532 nm, 10 ns laser pulses from a frequency doub...
