Xiaosheng Wang, Zhigang Chen, Jianke Yang
We report the first demonstration of embedded lattice soliton trains. Such solitons arise from the X-symmetry points in the first Bloch band but still reside (embedded) in the first band of a 2D photonic lattice.

Greatly enhanced power throughput from a "C"-shaped metallic nano-aperture for near field optical applications 大大提高功率吞吐量从“C”形金属纳米孔径近场光学应用
Xiaolei Shi, Hesselink, Thornton
Summary form only given. Metal apertures with sizes down to 100 nm can provide deep sub-wavelength optical resolution in the near field region and are proposed for various applications such as ultra-high density optical data storage, nano-structure sensors et al. Unfortunately, the power throughputs from these nano-apertures are typically very low and this power deficiency problem hinders the practical use of the apertures. To overcome this problem, we investigate how the power throughput changes when we change the aperture geometry, using a numerical finite difference time-domain (FDTD) method. To testify the simulation result, we carried out experiments in the microwave frequency range. The microwave wavelength is 5 cm, which is 50,000 times the incident light wavelength in the simulation. The apertures are fabricated in a 0.5 mm thick copper plate. An intuitive understanding for the power throughput enhancement from the "C"-aperture can be achieved by considering the "C"-aperture as a short "ridge-waveguide", which has the unique property that its cutoff wavelength is much larger than twice the size of the waveguide. This simple understanding has been investigated to be quantitatively valid by comparing the cutoff wavelength of the ridge-waveguide and the resonance wavelength of the "C"-aperture.
只提供摘要形式。尺寸小至100 nm的金属孔可以在近场区域提供深亚波长光学分辨率,可用于超高密度光学数据存储、纳米结构传感器等各种应用。不幸的是,这些纳米孔的功率吞吐量通常非常低,这种功率不足问题阻碍了这些孔的实际使用。为了克服这一问题,我们使用时域有限差分(FDTD)数值方法研究了当孔径几何形状改变时功率吞吐量的变化。为了验证仿真结果,我们在微波频率范围内进行了实验。微波波长为5 cm,是模拟中入射光波长的5万倍。这些孔是在0.5毫米厚的铜板上制造的。通过将“C”孔径视为一个短的“脊波导”,可以直观地理解“C”孔径对功率吞吐量的增强,其独特的性质是其截止波长远远大于波导尺寸的两倍。通过比较脊波导的截止波长和“C”孔径的共振波长,研究了这种简单的理解在定量上的有效性。

Quantum interactions of LG beams LG光束的量子相互作用
Andrews, D. Romero, Babiker, Bennett
Summary form only given. The aim of this work is to promote the development of a quantum framework for formulating the interactions of Laguerre-Gaussian beams and others of related structure, in which a helical wavefront confers an endowment with orbital angular momentum. We explore changes in selection rules in the context of non-linear processes, especially second harmonic generation and sum-frequency generation processes, and the effects of higher electric and magnetic multipoles. We evaluate the forces and torques that can act on molecules endowed with electric or magnetic multipoles.
