Solitons are solitary waves which have a particle like behavior as they maintain their shape when travelling at a constant speed and also that when a soliton interacts with another soliton then it retains its shape after emerging from the collision with a possible change in the phase shift [1]. A precise simulation is employed to simulate the generation of soliton pulses by using two techniques employing the Laser Pulse as a source as well as by using a Soliton Pulse generator. The respective techniques performance in terms of bit rate, optical fiber length, Q factor, BER, jitter and eye opening were studied. The outcomes from the simulations further clarify that the Soliton Pulse generation technique provides much effective pulse shape retention for longer communication distances as well as provide a better peak power, both of which are crucial factors for the data transmission to be done efficiently in any communication system so as to compensate for the noise and the distortion introduced in the system. Also the non-linear effect of Self Phase Modulation has General Terms

“…Thanks to the intrapulse Raman contribution of the silica, the central frequency of the pulse progressively shifts towards longer wavelengths, this frequency shift being basically controlled by the peak power of the initial pulse [5]. Such a spectral shift has been previously used for a wide range of photonics applications such as wavelength-tunable ultrashort sources [6], optical sampling [7], coherent anti-Stokes Raman scattering bioimaging [8] or analog-to-digital converters [9]. Here, we combine the SSFS process with a long-pass filter blocking the low-wavelength components, thus acting as an optical thresholder that efficiently discriminates the pulses according to their initial power.…”

We describe a fiber-based device that can significantly enhance the low intensity fluctuations of an ultrashort pulse train to detect them more easily than with usual direct detection systems. Taking advantage of the Raman intrapulse effect that progressively shifts the central frequency of a femtosecond pulse propagating in an anomalous dispersion fiber, a subsequent spectral filtering can efficiently increase the level of fluctuations by more than one order of magnitude. We show that attention has to be paid to maintain the shape of the statistical distribution unaffected by the nonlinear process.

“…To achieve spectral energy at wavelengths longer than provided by a given pump laser, one can use the soliton self-frequency shift to simply red-shift the laser pulse over a desired wavelength range. This can be done over 900 nm [2] and provides a basis for tunable lasers with applications including broadband spectroscopy [3] and coherent anti-Stokes Raman scattering (CARS) microspectroscopy [4]. ZBLAN fluoride (a mixture of zirconium, barium, lanthanum, aluminum, and sodium fluorides) fibres have been used to extend the supercontinuum spectrum beyond 4.5 µm [5].…”
