The non-subsampled Contourlet transform (NSCT) has not only characteristics of multi-scale, multidirection and anisotropy, like traditional wavelet transform and Contourlet transform, but also the good characteristics of shift-invariant. We draw the

A periodically poled LiNbO3 (PPLN) with homocentric semicircle domain structure is prepared, by which a high efficiency second harmonic generation with large angle acceptance is demonstrated. The angle acceptance and conversion efficiency of this PPL

The effective high-order quasi–phase-matching second- and third-harmonic generations were realized in a two-dimensional periodically poled LiNbO3 with rectangular lattice. The output spots lay at different symmetric places with respect to the input

A two-dimensional nonlinear photonic crystal of lithium niobate with rectangular lattice was fabricated. In this crystal, the quasiphase-matching conditions can be satisfied in different directions for different wavelengths. As a tunable optical para

Monodisperse colloidal SiO2 submicrospheres were prepared by hydrolysis and condensation of tetraethoxysilane. We measured various relative settle velocities of different aggregated submicrospheres and then developed a submicrospheres selection techn

We present a scanning electron microscopy (SEM) investigation of artificial opals prepared by the sedimentation of suspension with sub-micrometer silica spheres. An analysis of the SEM images confirms that the fcc stacking is the most stable phase fo

We demonstrate specular photonic "lattices" with random index variations at disordered positions of lattice sites. These amorphous lattice structures, optically induced in a bulk nonlinear crystal, remain invariant during propagation since they are c

Two-dimensional nonlinear photonic crystals of lithium niobate with square lattices were fabricated. In these crystals, efficient quasiphase-matched second-harmonic generation was demonstrated by using second-order quasiphase matching. As a mode-lock

The periodic disturbance in transmittance of polystyrene photonic crystal is detected in our experiment. The peak-to-peak intervals of the periodic disturbance vary with the wavelength. It is attributed to the propagation of the whispering gallery mo
