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.

Resonant coupling of excitons in strongly confined hybrid perovskite conjugated to InGaN quantum wells is observed. Temperature and time-resolved-photoluminescence (PL) reveal 10 times enhancement of recombination lifetime in strong-coupling regime due to resonant energy transfer.

Ultrahigh-Q (105-106) resonant modes of 10 sequentially coupled photonic crystal resonators are successfully demonstrated. Evaluated dispersion curves reveal a very small coupling factor (??0.0003), which corresponds to a very slow light mode.

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.

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.
