When a circularly polarized plane wave is normally incident on a slab of a structurally chiral material with local 4̄2m point group symmetry and a central twist defect, the slab can function as either a narrowband reflection hole filter for co–handed plane waves or an ultranarrowband transmission hole filter for cross–handed plane waves, depending on its thickness and the magnitude of the applie...

Highly accurate group delay measurements in long singlemode fibers were achieved over the full 1200-1600 nm spectral range by measuring phase shifts of a modulated lightwave. The high modulation frequency is shifted down to the kilohertz range using a second optical modulation at the fiber output end, so that low-frequency ultrasensitive detection and phase measurement can be performed with hig...

Surface waves can propagate on the planar interface of a linear electro-optic (EO) material and an isotropic dielectric material, for restricted ranges of the orientation angles of the EO material and the refractive index of the isotropic material. These ranges can be controlled by the application of a dc electric field, and depend on both the magnitude and the direction of the dc field. Thus, ...

The propagation of Dyakonov surface waves (DSWs) at the planar interface between an isotropic material and a linear electro-optic birefringent material can be dynamically controlled using the Pockels effect. The range of directions for DSW propagation has been previously found to be rather narrow. By careful choice of various parameters, this range of directions can be increased by more than an...

Generation of a giant pulse of Er:YAG laser is complicated mainly due to the properties of the Er:YAG active medium itself. It is caused by the short lifetime of the Er:YAG crystal upper laser level and a small gain for one pass of the radiation through the active medium. In our case, a specially designed LiNbO3 electrooptic shutter was used for Qswitching of Er:YAG laser. Brewster angles were ...

An innovative flash LIDAR (light detection and ranging) system with high spatial resolution and high range precision is proposed in this paper. The proposed system consists of a polarization modulating Pockels cell (PMPC) and a micro-polarizer CCD camera (MCCD). The Pockels cell changes its polarization state with respect to time after a laser pulse is emitted from the system. The polarization ...

We present an explicit sech-squared-soliton solution associated with the optical Pockels effect, achieved through generation of frequency combs via parametric down-conversion in microresonators quadratic nonlinearity. This soliton contrasts sech-soliton describing half-harmonic field limit large index mismatch, and cascaded-Kerr effect. predict differences spectral profiles powers solitons, rep...
