nonlinear Bragg diffraction -- nonlinear photonic lattice -- second harmonic -- generation -- femtosecond pulses
Аннотация: The frequency doubling of femtosecond laser pulses in a two-dimensional (2D) rectangular nonlinear photonic lattice with hexagonal domains is studied experimentally and theoretically. The broad fundamental spectrum enables frequency conversion under nonlinear Bragg diffraction for a series of transverse orders at a fixed longitudinal quasi-phase-matching order. The consistent nonstationary theory of the frequency doubling of femtosecond laser pulses is developed using the representation based on the reciprocal lattice of the structure. The calculated spatial distribution of the second-harmonic spectral intensity agrees well with the experimental data. The condition for multiple nonlinear Bragg diffraction in a 2D nonlinear photonic lattice is offered. The hexagonal shape of the domains contributes to multibeam second harmonic excitation. The maximum conversion efficiency for a series of transverse orders in the range 0.01%-0.03% is obtained.

Аннотация: In search of new nonlinear optical crystals for the mid-IR range, we grew single crystals of LiGa0.55In0.45Te2 (LGITe) of optical quality; its structure was established, and the spectroscopic properties were studied. LGITe crystallizes in a tetragonal chalcopyrite-like (I4̅2d) structure at 667 ± 5 °C. Crystals are transparent in the 0.76–14.8 μm spectral region with some absorption bands related to OH/H2O and Ge–O vibrations. Analysis of the Tauc plots showed that LGITe is a direct band gap semiconductor with the band gap Eg = 1.837 eV at 300 K. The Raman spectrum for LGITe is very similar to that for LiGaTe2: the most intense band A1 near 120 cm–1 corresponds to the Li–Te vibration. DFT calculations were carried out for the first time to simulate the energy band structure (band gap ∼1.67 eV), density of states (DOS), birefringence (0.049 at 2 μm), and nonlinear susceptibility (d14 = d36 = −48.73 pm/V). For ternary LiInTe2 these parameters are Δn = 0.007 and d14 = d36 = −61.4 pm/V, respectively. The calculated optical properties indicate that LiGa0.55In0.45Te2 is a promising mid-IR nonlinear optical crystal with nonlinear parameters higher than those of LiGaTe2.

Аннотация: Coupling between the defect mode of a cholesteric liquid crystal and the localized mode of a cholesteric liquid crystal-phase plate-metal structure is theoretically demonstrated. It is shown that the transmittance spectrum can be tuned by changing the twist-defect angle and helix pitch, which are governed by external factors. The spectra for different circular polarizations of the incident light are different; specifically, at the nondiffracting polarization, there is no defect-mode transmittance peak.

Аннотация: Backward electromagnetic waves are extraordinary waves with contra-directed phase velocity and energy flux. Unusual properties of the coherent nonlinear optical coupling of the phase-matched ordinary and backward electromagnetic waves with contra-directed energy fluxes are described that enable greatly-enhanced frequency and propagation direction conversion, parametrical amplification, as well as control of shape of the light pulses. Extraordinary transient processes that emerge in such metamaterials in pulsed regimes are described. The results of the numerical simulation of particular plasmonic metamaterials with hyperbolic dispersion are presented, which prove the possibility to match phases of such coupled guided ordinary and backward electromagnetic waves. Particular properties of the outlined processes in the proposed metamaterial are demonstrated through numerical simulations. Potential applications include ultra-miniature amplifiers, frequency changing reflectors, modulators, pulse shapers, and remotely actuated sensors.
