Ø  <!–[endif]–>SUMMARY OF THE RESEARCH CONTRIBUTION BY Prof.K.PORSEZIAN

 

Prof K. Porsezian (KP) has been one of the most active workers in the area of Nonlinear Dynamics and is investigating the soliton and modulation instability (MI) aspects encompassing magnetic systems, nonlinear fibre optics, bulk materials, photonic crystal fibres, Bose-Einstein condensates, metamaterials and related areas. His investigations have advanced the state of knowledge in the subject considerably and contributed to the better understanding of application of the concept of soliton and MI in the above areas.

 

Contribution to Magnetic Systems

 

KP has investigated the dynamics of Heisenberg Ferromagnetic spin chain including the effect of discreteness of lattice in the classical continuum limit. He showed that the discreteness effects in higher orders destroyed lower order coherent structures and demonstrated that solitons were possible only for specific choices of biquadratic parameters [2]; Improved upon the earlier models with a new soliton possessing discrete magnetic system [3]; Showed that site dependent and radially symmetric magnetic systems admitted solitons; but only when suitable inhomogenities are added [4,7].

 

Contribution to Nonlinear Fibre Optics and other Areas of Physics

 

Considering the higher order optical effects, Porsezian explored the soliton propagation and MI conditions in both resonant, nonresonant and birefringent fibres BEC, metamaterials and bulkmaterials and proposed several soliton models and new novel ideas in MI, which find applications in optical communication and the soliton propagation in birefringent fibre with all the above higher order effects[12,16-24,29,45-144]. He analyzed the influence of initial phase modulation on soliton-soliton interaction in a lossy fiber [50, 51, 56] and also elucidated the condition under which MI sets in, in the presence of SRS [67]. Using projection operator method, he investigated the dynamics of femtosecond pulse propagation through the birefringent fibre and observed that the impact of SS and SRS scattering on chirp of the pulses decreases/increases in AD/ ND regime [93].

 

KP’s most noteworthy contribution is the prediction of suitable dispersion map forms under the complete suppression of soliton-soliton interaction scenario [80,90,105]. He demonstrated a novel pulse amplification technique, based on exact multi solitons interacting with variable dispersion, nonlinearity and gain or loss and with the inclusion of SRS [82]. Further, soliton dispersion management and self-similar solutions pertaining to the effect of varying dispersion with external harmonic oscillator potential for chirped solitons have been investigated with emphasis on the various aspects of dispersion profiles and obtained many novel results [90,92,96]. He demonstrated a novel pulse compression technique based on exact soliton solutions to nonlinear Schrödinger type equations interacting with a source, variable dispersion, nonlinearity and gain or loss [69,73,122].

 

KP obtained new type of Dark-in-the-Bright solution also called dipole soliton for the higher-order nonlinear Schrödinger (HNLS) equation with non-Kerr nonlinearity and investigated the stability of the solitary wave solution under some initial perturbation on the parametric conditions.  He investigated the exact analytical self-similar bright – and dark optical solitary wave solutions of the nonlinear Schrödinger equation with localized inhomogeneous cubic-quintic nonlinearity by employing some new type of similarity transformation where one can compress and amplify the bright- and dark solitons of the inhomogeneous cubic-quintic nonlinear Schrödinger equation to a desired width and amplitude in a controllable manner[132].

 

KP obtained the MI conditions required for the evolution of USPs in an asymmetric dual-core fiber and also investigated the ensuing nonlinear evolution of pulses in the ND regime and a regular chain of stable bright solitons in the AD regime which can be used as a source of RZ pulses for optical telecommunications [75]. He investigated the MI of symmetric and asymmetric CW solutions with the constant amplitude of two linearly coupled complex Ginzburg-Landau equations with the cubic-quintic nonlinearity, which explains a laser based on a dual-core fibre [87].  KP investigate the dynamics and steering characteristics of optical pulse propagation at 850 nm through photonic crystal fibre (PCF) using the projection operator method (POM), where the propagation of Gaussian pulse in the twin core fiber is analyzed using CNLSE. The efficient switching of different liquid filled system is analyzed [137].

 

By considering the influence of dispersion up to the sixth order on the scalar MI process of ND and AD fiber, he elucidated the dichotomy between the odd order and even order dispersion terms in their influence on the MI and demonstrated that independent consideration of each even order dispersion leads to the increase in spacing between the side bands and the gain spectrum is dominated by the influence of second and fourth order dispersion effects. In the ND regime, MI occurs only for negative value of fourth order dispersion and analyzed the interrelation of SRS and MI [78]. By means of a technique based on average dispersion decreasing dispersion managed fibres, achieved both a complete suppression of the side band frequency shifts and a fine control of the MI frequencies, without any compromise in the MI power gain [84]. He demonstrated that a fibre with periodically varying dispersion can substantially improve the power gain of nonconventional sidebands induced by periodic fluctuation of dispersion [89]. KP investigates the unconventional MI process like the generation of new MI bands under the impact of higher order dispersion.  The significant of those is the investigation of MI under the non-instantanesous nonlinear response and saturation of nonlinearity, where new MI spectral bands with infinite bandwidth are observed.

 

KP investigated the existence of bright and dark solitons in coupled photorefractive media [66]. Propagation of light beam with cubic-quintic (CQ) nonlinearity has been studied both analytically and numerically, both being in excellent agreement. The existence of stable light bullets in a medium with CQ nonlinearity and self-defocusing effect of free electrons due to plasma formation has been proved [70]. He demonstrated numerically that the three-dimensional spinning solitons are unstable and the multiphoton ionization effect may stabilize the spinning light bullets in the CQ model [79]. He proposed and investigated, using numerical simulation and experimental technique, the evolution of beam through a directional coupler formed in a photopolymer system [94,97]. Considering pulse propagation in fibre Bragg grating (FBG), explained the symmetry breaking instability and optical switching [59, 61-63]. The condition for MI in nonlinear management (NM) FBG were demonstrated and arrived at two main results: (i) MI occurs only for finite values of the total input power for both AD and ND regimes; and (ii) The gain spectrum changes profusely for comparatively smaller and comparatively larger values of the NM coefficient [67,72,74]. The conditions for the occurrence of cross-phase MI in the ND regime, which occurs as a result of group velocity mismatch between the linearly polarized Eigen states, are determined. He also explored the MI conditions for nonlinearity management through dynamic Bragg grating and investigated the existence of gap soliton solutions through MI [98].

 

KP analyzed the MI of two components of Bose – Einstein condensates in a quasi-one-dimensional geometry [71] and investigated the MI of steady state solutions with constant amplitude in the model of averaged coupled GP equations under the Feshbach resonance management [87,95,106]. KP successfully analyzed the MI in Spinor BECs. A detailed analytical and numerical treatment of Modulational instability in F=2 spinor condensate is presented and the spin-mixing dynamics during evolution of the spinor condensate is dealt [134].

 

KP investigated the influence of linear and nonlinear effects in PCF for different air hole size and successfully demonstrated the generation of higher order solitons in PCF near the visible wavelength regime [86,123]. Also the existence and stability of solitons on the background of a continuous wave and conditions for MI in negative index material [100] have been investigated. The most notable contribution of KP is the analysis of supercontinuum generation using Soliton Fission and Modulational Instability [120,124,131].  By making use of the well – known MI, he went beyond the scope of ordinary MI process and identifies the evolution of SCG from MI.  The most significant of all is the investigation of Instability induced SCG in saturable nonlinear media. Apart from saturable nonlinear media KP also analyzed intensively the effect of slow nonlinear response in the liquid filled PCF, where fibre design and the calculation of fiber parameters are analyzed systematically [122,123].  Particularly, KP interested much in the investigation of the impact of the delayed Raman response in the MI spectra.  By deriving suitable model equation, he extensively analysed the impact of higher order dispersion and the nonlinear relaxation in the instability spectra of both scalar and vector MI [139 ,140].
