“…The amplification bandwidth is 38 nm, which, to the best of the authors' knowledge, is the widest amplification bandwidth ever reported from the dual-wavelength pumping scheme. This also corresponds well to the suggested bandwidth of 40 nm based on the simulation result using dual-pump wavelength in [8]. Based on the experimental results, gain saturation is very minimal for the distributed Raman amplifier, as also reported in [13].…”

In this paper, a 38‐nm wideband gain‐flattened distributed Raman amplifier utilising two pump wavelengths is experimentally demonstrated. The pump combination of 1430 and 1456 nm with 26‐nm spacing has enabled a gain flatness of less than 1.1 dB at a Raman on‐off gain of 10 dB. The flat gain is obtained through a careful pump‐power adjustment between these two pump wavelengths without any gain‐flattening filters. The 38‐nm bandwidth covers signal wavelengths from 1530.33 to 1568.78 nm. © 2006 Wiley Periodicals, Inc.

Analysis is carried out for a single span wavelength division multiplexing (WDM) transmission system with distributed Raman amplification to find the effect of amplifier induced crosstalk on the bit error rate (BER) with different system parameters. The results are evaluated in terms of crosstalk power induced in a WDM channel due to Raman amplification, optical signal to crosstalk ratio (OSCR) and BER at any distance for different pump power and number of WDM channels. The results show that the WDM system suffers power penalty due to crosstalk which is significant at higher pump power, higher channel separation and number of WDM channel. It is noticed that at a BER 10 −9 , the power penalty is 8.7 dB and 10.5 dB for the length of 180 km and number of WDM channel N = 32 and 64 respectively when the pump power is 20 mW and is higher at high pump power. Analytical results are validated by simulation.

“…Although various numerical optimisation methods have already been proposed (Yan et al 2001, Perlin and Winful 2002, Muktoyuk et al 2004, Liu and Li 2004, Hu et al 2004) each with their specific advantages and limitations, development of new approaches is of interest to address the variety of applications and practical boundary conditions and constraints.…”

Simple design method for gain-flattened three-pump Raman amplifiers

We propose a simple and efficient approach to the design of 3-wavelength backward-pumped Raman amplifiers with increased gain flatness over a wide spectral band. Three different methods dealing with the optimization of one or two different simple parameters are studied. Various examples are provided for illustration, and the dependence of both amplifier gain and gain flatness with pump power is shown. Gain flatness in the spectral range of 1,520-1,595 nm of about 1 dB for a 7.5 dB gain and of 1.8 dB for a 13.5 dB gain is demonstrated using only three pumps with wavelengths within the 1,420-1,480 nm interval.
