“…Noteworthy, the influence of β 4 and β 6 is more significant when signal is launched at the wavelength far from the pump. Yet, the effect of β 6 sign is hardly can be observed because of β 6 small value and the effect is almost disappeared if it is combined with both positive or both negative values of β 2 and β 4 , since their impact are dominant in (6). To summarize, the combination of β 2 > 0, β 4 > 0 and β 6 > 0 is resulted in a poor gain spectrum as the phase-mismatch is very large for this combination.…”

Abstract. This paper investigates the influence of different combinations of second-order (β 2 ), fourth-order (β 4 ) and sixth-order (β 6 ) dispersion coefficient signs (negativity/positivity) to the fiber optical parametric amplifier gain performance. The numerical simulation has exploited the fourth-order Runge-Kutta method to solve the coupled amplitude equations which basically represent the parametric process of four-wave mixing. In the normal regime at which β 2 is positive, the fiber optical parametric amplifier exhibits a poor gain spectrum and it is well performed once the pump is presumed to be in anomalous regime i.e. β 2 is negative. The effect of β 4 is significant when the signal wavelength is further from the pump wavelength and a wide amplification bandwidth is produced when the fiber have positive β 4 in the anomalous regime. As for β 6 , unfortunately in this simulation its influences are hardly can be seen probably because of its small value regardless its sign, but, from phase-mismatch equation it is shown that its impact is prominent when the signal is positioned way far from the pump. All in all, this shown that the signs combination of the higher-order dispersion coefficients are significant in order to optimize the FOPA amplification bandwidth.

The use of fiber optic for telecommunication system has widely developed because of limitations on communication ranges and methods for information demands. In the application of optical fiber communications, signal strength is reduced due to attenuation, absorption and dispersion effects of source, structure, and geometry of fiber, even for single mode fiber, these problems still exist. In order to investigate these phenomena, this paper designs and operates a simple optical design consisting of wavelength division multiplexing (WDM) which is able to multiplex various wavelength sources to one fiber optic by using various source wavelengths. This mechanism allows a bidirectional communication with several or more fibers without any interference. The output will describe the bit error rate (BER) and Q-factor and using two samples of Semiconductor Optical Amplifier (SOA) and Fiber Raman Amplifier (FRA). The simulation evaluates these amplifiers by manipulating the frequency of bandwidth until 50 GHz, a low BER corresponding to large Q-factor is reached. The BER value for SOA device is 7.59 Â 10 −16 and 1.54 Â 10 −27 for SOA device respectively for a bandwidth of 50 GHz. These data depict that SOA is able to launch the wavelength to high performance than that of FRA device. Both optical amplifiers describe better performances in term of the value of BER and Q-factor having much smaller than 10 −12 and larger than that of 6 respectively for a distance of 120 km for SOA and 100 km for FRA.

The impact of pump parameters on dual-pump (2-P) fiber optical parametric amplifier (FOPA) is investigated. The four-wave model of coupled amplitude equations with fiber losses and pump depletion are solved numerically for the calculation of the parametric gain. Simulation results indicate that an increase in pump powers does not only enhances the parametric gain but also flattening the amplification bandwidth. Moreover, separating the pumps wavelengths further from each other can also improve the flatness of the bandwidth. Besides that, the parametric gain flatness can be improved when the separation between the pump central wavelength and zero-dispersion wavelength is small. In essence, the optimal performance of 2-P FOPA can be achieved when the pump parameters are carefully tailored.
