“…It has been shown that pulses generated via SSFS are usually chirp-free, with nearly transform-limited duration [23]. Nevertheless, we verified the pulse shape and duration via interferometric autocorrelation using a standard Michelson interferometer with a 2-mm thick BBO crystal for second harmonic generation (SHG).…”

We demonstrate a broadband mid-infrared (MIR) frequency comb source based on difference frequency generation (DFG) in periodically poled lithium niobate (PPLN) crystal. Mid-infrared radiation is obtained via mixing of the output of a 125 MHz repetition rate Ybdoped fiber laser with Raman-shifted solitons generated from the same source in a highly nonlinear fiber. The resulting idler is tunable in the range of 2.7 -4.2 μm with average output power reaching 237 mW, and pulses as short as 115 fs. The coherence of the MIR comb is confirmed by spectral interferometry and heterodyne beat measurements. Applicability of the developed DFG source for laser spectroscopy is demonstrated by measuring absorption spectrum of acetylene at 3.0 -3.1 μm.

“…In the case of spatial soliton the natural property of light which is to disperse in space is being compensated by the nonlinearity of the medium in such a way that higher intensity part of an optical beam which is typically at the center of the employed Gaussian beam, increase a value of refractive index of medium forming de facto a core of waveguide that is responsible to confine in reverse a dispersed light to the middle of the beam itself [5]. It can be easily intuitively understood that if the self induced nonlinearity [2] is too high the beam will get focused and on the other hand if it is very small or none, beam will disperse in space -a prevailing situation in many cases where a beam does not have enough power density to induce nonlinearity in a medium.…”

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

“…Unfortunately, solitons suffers various higher order effects like third order dispersion (Elgin et al 1995), intra pulse Raman scattering (Golles et al 1997) and self steepening (Lee 2008;Voronin and Zheltikov 2008;Trippenbach and Band 1998) which needs precise control on system design. The Third Order Dispersion (TOD, β 3 ) can be treated as perturbatively small at longer region from zero dispersion point, but becomes a matter of interest at or near zero dispersion point of the optical fiber.…”

In this paper, we demonstrate the effect of soliton interaction in 100 Gbps telecommunication system implemented with four types of practically deployed telecom fibers like conventional single mode fiber, Alcatel's teralight fiber, Lucent's truewave plus fiber (TW+) and large effective area fiber. With the initial relative spacing of in-phase soliton chosen as q = 5.28, the characteristic soliton interaction point and the collision length with respect to various fiber types were studied. The practical undesirability of soliton interaction is noted for three collision period with all types of fibers to characterize the degradation after successive collisions. Besides studying the soliton interaction, we have also demonstrated its effect in telecommunication system degradation with the performance measures like Quality factor and eye patterns. Eye patterns were used to picture the mechanism of soliton interaction within the collision length. It was found system implemented with TW+ fiber of low dispersion co-efficient comparatively has long interaction length and suitable for long distance transmission without dispersion compensation.
