Scattering of plane monochromatic waves on quasiperiodic layered structures is considered. Exact solutions for complex amplitudes of reflected and transmitted waves are found by method of transmission matrices. Influence of connection of lumped elements on resonance properties is investigated. Hysteresis behavior is observed for case of Kerr nonlinearity.

This paper reviews our recent activities on nanophotonics based on a photonic crystal (PC)/quantum dot (QD)-combined structure for an all-optical device and a metal/semiconductor composite structure using surface plasmon (SP) and negative refractive index material (NIM). The former structure contributes to an ultrafast signal processing component by virtue of new PC design and QD selective-area-growth technologies, while the latter provides a new RGB color filter with a high precision and optical beam-steering device with a wide steering angle.

We report an enhanced experimental set-up that allows fast and accurate determination of refractive indexes in optical materials. The set-up is equipped with the high-precision sample positioning system and sensitive detector for the registration of interference fringes shift. Additionally, an approach that can be utilized in order to eliminate the error caused by non-parallel sample edges is discussed. The results of the refraction index measurements in lithium niobate are presented.
