“…7). This shift is in good agreement with the works of Maksymov et al [36], Bhargava and Suthar [37], and Meng et al [38]. For the 1D NLPC, the shift of the band structure can be explained using Scalora et al's approach [39].…”

“…In these devices, the refractive index is changed by a high-intensity incident beam to dynamically control the transmission of light. Under this condition, the optical limiting is achieved by modifying the incident intensity while the all-optical switching requires an additional strong pump beam to control the switching of a weak probe signal tuned to the band gap region [36,37]. In Fig.…”

Nonlinear effect on optical properties of one-dimensional photonic crystal (1D-PC) of the type (HL) n (LH) m (LLHH) k was investigated. It is an asymmetric hybrid Fabry-Perot resonator type of 1DPC structure which is composed of linear (H layers) and nonlinear (L layers) materials. The linear and nonlinear transmission spectra are graphically illustrated using a numerical approach based on the Transfer Matrix Method (TMM). Results show the appearance of a Perfect Transmission Peak (PTP) in the photonic band gap which makes the structure constitute a monochromatic filter. By analyzing this PTP it is shown that the Full-Width at Half-Maximum (FWHM) depends not only on the number of symmetry layers of the studied 1D-PC but also on the refractive index of the nonlinear layers. The change of the refractive index (Kerr effect) causes a dynamically shift in the band gap including the resonance peak. As a result, such a structure has the potential to be used for designing optical filters and nonlinear optical devices.

“…In this way, several works propose the combination of photonic crystals with nonlinear optical (NLO) materials or liquid crystal (LC) materials (Busch and John 1999;Takeda and Yoshino 2002;Maksymov et al 2004). In the former case, a high-intensity control signal with frequency outside the bandgap changes the properties of the crystal (Cuesta-Soto et al 2004).…”

“…Second, these liquid crystals have a small birefringence in its anisotropic state (E7 liquid crystal: n o = 1.52, n e = 1.70, n = 0.18), which results in an even smaller tunability range. Consequently, in order to obtain actual working devices, such as couplers (Liu and Chen 2004), Y-shaped waveguides (Takeda and Yoshino 2003) or optical circuits (Maksymov et al 2004), it is determinant to know how to obtain the optimal design from the available materials.…”

In this work we study the optimization of the tunability range in waveguides based on two-dimensional silicon photonic crystal infiltrated with liquid crystal. The analyzed structure consists of a two-dimensional silicon photonic crystal with a triangular lattice of circular holes where a line of scatterers in the direction -K has been replaced by a line of circular holes with different radius infiltrated by E7 liquid crystal. To this end, we use the plane-wave expansion method considering anisotropy and modelling supercells to account for the lattice defects that define the waveguide. Finally we study the field distributions of the guided modes in order to analyze their symmetries and confinement.

“…Using a three-dimensional finite-difference timedomain method [22,23], we investigate nonlinear characteristics of the tapered nanoantenna by exciting it with the pump wave at frequency 190.8 THz and the signal wave at 197.3 THz (both z-polarized, see Fig. 1).…”

Cascaded four-wave mixing in tapered plasmonic nanoantenna

We study theoretically the cascaded four-wave mixing (FWM) in broadband tapered plasmonic nanoantennas and demonstrate a 300-fold increase in nonlinear frequency conversion detected in the main lobe of the nanoantenna far-field pattern. This is achieved by tuning the elements of the nanoantenna to resonate frequencies involved into the FWM interaction. Our findings have a potentially broad application in ultrafast nonlinear spectroscopy, sensing, on-chip optical frequency conversion, nonlinear optical metamaterials and photon sources.
