“…In the dc-V experiment on diamond the IR peak that appeared at ω = 1332.6 cm −1 had narrow peak width less than 5 cm −1 and the symmetric line shape. 7,8 In contrast the ∆σ 1 (E) hump in LFO is very broad and should be considered as an absorption band rather than a peak. Also the ∆σ 1 (E)-band has strongly asymmetric shape.…”

We applied dc-voltage (V) to LuFe2O4 single crystal and measured the V-dependent optical reflectivity. As V increases an optical absorption band appears at mid-infrared frequency range which we could identify to result from the dc-electric (E) field. We discuss possible connection of this novel electro-optical effect with the strongly correlated states in LuFe2O4. In the mean time a reflectivity level change is seen in the IR ∼ visible frequency range by the V-application due to the Joule heating of the sample. 1 This phenomenon, termed as the "electronicferroelectricity", is distinguished from the traditional ferroelectricity where the electric polarization is induced by the displacement of charged ions as known in, for example, BaTiO 3 . As temperature decreases the localized spins of the Fe 2+ and Fe 3+ show the ferrimagnetic ordering at T N = 240 K. The ferroelectricity and the magnetism are coupled with each other as revealed by recent X-ray scattering experiment.2 A large magneto-dielectric change was observed

“…The amplitude of input CW Stokes signal was chosen E 0 s = 10 −5 E 0 l . Numerical investigations were done for the model with parameters typical for calcite [34] and diamond [35][36][37] Figure 10.7b displays a shortened Stokes output pulse that has surpassed the inhomogeneously depleted and broadened fundamental pulse (zoomed in the inset). The simulations also show that shapes of the output Stokes and fundamental pulses differ and vary significantly depending on the intensity of the input fundamental wave.…”

Extraordinary properties of nonlinear optical propagation processes in double-domain positive/negative index metamaterials are reviewed. These processes enable coherent energy exchange between ordinary and backward electromagnetic waves, which allows huge increase of frequency-conversion efficiency at second harmonic generation, three-wave mixing and optical parametric amplification. Striking contrasts with properties of the counterparts in ordinary materials are outlined. Particularly, exotic features arise for amplification and generation of counter-propagating short pulses. Novel class of materials, which enable such processes through electromagnetic waves with negative group velocity, are proposed. The possibility to mimic such processes in readily available crystals that support elastic backward waves (optical phonons) is shown. The concepts of unique photonic devices such as data processing chips, tunable nonlinear-optical mirrors, filters, switches and sensors are discussed. IntroductionOptical negative-index materials (NIMs) form a class of electromagnetic media that promise revolutionary breakthroughs in photonics. The possibilities of such breakthroughs originate from backwardness, the exotic property that electromagnetic waves (EMWs) acquire in NIMs. Unlike ordinary positive-index materials, the energy flow, S, and the wave-vector, k, become counter-directed in NIMs that determines their unique linear and nonlinear optical (NLO) propagation properties. The appearance of backward electromagnetic waves (BEMW) can be explained as follows. The direction of the wave-vector k with respect to the energy flow S
