“…Photonic crystal fiber due to their extraordinary properties compared to standard optical fibers has drawn the attention of many researchers [1]- [4]. These properties include chromatic dispersion [5], birefringence [6], ultra low loss [7], endless single mode propagation [8], large nonlinear co-efficient [9] and effective mode area [10]. In conventional fiber, achieved birefringences are very low due to very low refractive index contrast.…”

Photonic crystal fiber (PCF) structures with do-octagonal geometry have been studied. These do-octagonal PCF structure have smaller circular holes arranged in rhombic fashion at its centre. Moreover, these small holes are doped with materials like butanol, ethanol, methanol and propanol. Do-octagonal PCF structures doped with methanol and air filled structure report very high birefringence. Ultra flattened zero dispersion has been achieved by all the simulated structures. Besides, low confinement loss and large nonlinearity have also been reported. Numerical simulation for supercontinuum generation has been performed. Supercontinuum spectra obtained for peak power 1 kW, 2 kW, 5 kW and 10 kW are 650 nm, 950 nm, 1450 nm and 2050 nm respectively.

“…are present like in any other fiber optic link. The CD is one of the significant linear impairments in fiber optical communication system whose detail description can be obtained in [14], [15]. Most importantly, CD and nonlinearity associated with modulator and square law photo detector are the major factors for impairments in RoF systems.…”

“…Furthermore, it is also possible to modify the structural features to suit a given NLO response . Therefore, they are of use in many areas of modern technology like telecommunications, optical signal processing, high‐end devices,, ultra‐fast data transmission‐storage systems, and integrated laser biomedical technologies . The NLO properties of D‐π‐A systems including BODIPY,, carbazole,, coumarin, triphenylamine, and julolidine donor containing dyes are extensively studied by means of the electric field induced second harmonic generation (EFISHG), hyper Raleigh Scattering (HRS) technique, Z scan, solvatochromic model, and DFT.…”

Three push-pull rhodanine-arylamine based D-π-A dyes (2a-2c) are prepared to study the effect of donor on electronic, linear and nonlinear optical properties. The dyes, 2a,2b and 2c have a vinyl spacer conjugated with triphenylamine, julolidine, and carbazole donors respectively, with a methoxy group and rhodanine-3-acetic acid. The dyes exhibited solvent dependent absorption-emission up to the red region with large Stokes shifts (2a = 77-130 nm). This dyes possess charge transfer characteristics as established by transition dipole moment (μ eg ), dipole moment ratio (μ e /μ g ), Generalised Mulliken-Hush analysis, and electron distribution (DFT). The non-linear optical study revealed that quadratic hyperpolarizability (μβ CT ) are 1098.9 (2a), 515.0 (2b) and 339.6 x 10 -48 e.s.u. (2c) depending on donor strength. The intrinsic hyperpolarizabilities fall below b int 0 ¼ 10 À 3=2 limit i.e. less than unity. Solvatochromic two-level model is used to study the trends in two photon cross-section (σ2PA). Solvatochromic two-level model is used to study the trends in two photon absorption cross-section (σ2PA). The dye 2a exhibited high σ2PA, 216 GM (λ max 485 nm and 564 nm). The dyes 2a and 2c with analogue dye 3a show reverse saturable absorption (RSA) therefore, show positive third order nonlinear absorption coefficient, β and reasonable values of third order nonlinear susceptibility and high laser damage threshold. The Re χ (3) factors are responsible for the high values of χ (3) in the range of 0.77 to 8.09 x 10-12 e.s.u. Therefore, this material would serve as good candidate in the photonic application.
