An experiment to determine the correlation of power in effect of four wave mixing (FWM) by obtaining the linearity of power towards FWM formation. A fibre ring laser configuration consists of amplifier set up and arrangement of FBGs is described. Encouraging results obtained from the set up proves the relations of power variable perspective which associated through FWM generation.
This paper presents a review of novel methods that have been proposed by many authors for nonlinear optical effects suppression in WDM systems. Among the major nonlinear optical effects in WDM systems include nonlinear crosstalk, cross-phase modulation (XPM) and four wave mixing (FWM). These nonlinearities will degrade the performance of WDM systems particularly at bit rates higher than 2.5 Gbit/s...
An integrable all-optical clocked D type flip-flop is demonstrated exploiting SOA-based transparent all-optical SR latch. Nonlinear effects of four wave mixing and cross gain modulation are used for optical logic gate operations.
An all-optical counter is presented using cascaded stages composed by SOA fiber laser based optical flip-flops and SOA four wave mixing AND logic gates. Two-bit all-optical pulse counting and optical frequency division are demonstrated.
We present an RF-driven two-stage 40 GHz RZ pulse source based on self-phase modulation and a fiber optic parametric amplifier, for generation of 1.1 ps pulses, and demonstrate generation of OTDM data up to 320 Gb/s.
We have experimentally, for the first time, demonstrated one-pump optical fiber parametric amplification (OPA) in bismuth-oxide-based highly nonlinear fiber (Bi-HNLF), and realized narrowband (0.75 nm) and tunable gain spectrum as high as 58 dB.
This paper investigates the first demonstration of linearization of semiconductor optical amplifier (SOA) using feed forward linearization. For improving the linearity and suppressing the four wave mixing (FWM) of SOA the amplifier uses the feed forward technique. This technique should be applicable to any microwave or even millimetre frequency band and any externally modulated laser. Link performance...
Wavelength division multiplexing (WDM) can give two benefits at the same time: enhancement of transmission capacity and increase in flexibility in optical network design. It is possible to build long distance transparent optical transmission links without electrical regenerators with the help of erbium-doped fiber amplifiers (EDFAs). In such systems, fibre nonlinearities are likely to impose a transmission...
We report that pump-noise induced FWM effects can be serious for some NZ-DSF fibres using distributed Raman amplification. Moreover, we find that such an effect strongly depends on the spectral structure of the pump, and can be suppressed by expanding the effective spectral width of the pump
