All-optical switching of defect mode in two-dimensional nonlinear organic photonic crystals

Applied Physics Letters (2005)

Xiaoyong Hu Qihuang Gong Yuanhao Liu Bingying Cheng Daozhong Zhang

An all-optical switching is demonstrated by use of defect mode in two-dimensional nonlinear photonic crystals made of polystyrene. Transmittance contrast of about 70% is achieved for the probe light. The dynamical shifts of the defect mode induced by pump intensity are measured and analyzed in detail. It is found that the defect mode shifts 5 nm under the excitation of 18.7GW∕cm2 pump intensity, which is in agreement with the theoretical predictions. Time response of the optical switching is smaller than the laser pulse of about 10 ps.

Second-harmonic generation in two-dimensional periodically poled lithium niobate using second-order quasiphase matching

Applied Physics Letters (2003)

Peigen Ni Boqin Ma Xuehua Wang Bingying Cheng Daozhong Zhang

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-locked Nd:yttritium–aluminum–garnet laser at 1064 nm with 35 ps pulse was used, we obtained an average power of 0.86 mW at 532 nm with 2.73 mW input, which corresponds to 42% internal conversion efficiency. The variations of second-harmonic output with crystal temperature and incident angle were measured. In addition, the relation between the second-harmonic output and reversed duty cycle was studied. All the experimental results are well consistent with simulations.

Two-dimensional periodically poled LiNbO3 nonlinear photonic crystal

Acta Physica Sinica (2003)

Ni Pei-Gen Boqin Ma Bingying Cheng Daozhong Zhang

A two-dimensional periodically poled lithium niobate crystal with a 13.64 μm period was fabricated. The inverted duty cycle was about 23%. The second harmonic output for the second-order quasi-phase-matching (QPM) against the input was measured. The maximum second harmonic internal conversion efficiency was higher than 40%. All results implied that the second-order QPM could be used to obtain high-frequency conversion efficiency. Compared with the first-order QPM, the second-order QPM can reduce the requirement for the poling technique and the mask fabrication.

Non-near-field focus and imaging of an unpolarized electromagnetic wave through high-symmetry quasicrystals

Optics Express (2007)

Xiangdong Zhang Zhiyuan Li Bingying Cheng Daozhong Zhang

The focus behaviors of electromagnetic wave through two-dimensional (2D) high-symmetry photonic quasicrystals (PQCs) have been investigated by using exact multi-scattering numerical simulation. We have found that the high-symmetry PQC flat lenses possess universal feature for non-near-field focus of two kinds of polarized waves. That is to say, the non-near-field focus for two kinds of polarized waves can be realized by using these flat lenses, which are consisting of 12-fold, 10-fold and 8-fold 2D PQCs with the same structures and parameters. Such a superior feature originates from higher rotational symmetry and negative refraction in the PQCs. Thus, potential applications of such a phenomenon to optical devices can be anticipated.

Two-dimensional crystalline structure

Conference on Lasers and Electro-Optics (1994)

Wei Hu Bingying Cheng Junhui Yang Zhaolin Li Daozhong Zhang

Creating a periodic array of micron size dielectric spheres with micron lattice constant in optical standing wave field is a promising method for fabricating photonic crystals, which was introduced by Bums et al. 4 years ago. They have successfully observed planar arrays of polystyrene sphere of 3.4 μm in diameter and the spaces between spheres were about 5 μm. Here we present the experimental studies on crystallization of polystyrene spheres in an optical standing wave matrix, similar to Bums, but the diameters of the spheres and lattice constant are reduced to submicron. This can lead to a realization of photonic crystal, which will be effective in a visible light range.

Transmission modulation in the passband of polystyrene photonic crystals

Applied Physics Letters (2003)

Honglian Guo Hongyi Chen Peigen Ni Qi Zhang Bingying Cheng

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 mode in polystyrene spheres. The results show that the periodically arrayed particles may affect light transfer outside the gap band, which implies the possibility in applications of photonic crystal films.
