Nano cavities based on silicon and indium phosphide materials have been comparedin this study, considering field intensity enhancement factor. The results of FDTD based simulations declare that the Si nano-cavity improves confined optical field about 7.7 times higher than the InP based nano-cavity. The introduced dielectric nano-cavities support resonance wavelength at about λ=1.55 μm.

This paper aims to explore the antibacterial property of nano Ag/TiO2 coating bracket for the common bacteria in oral cavity, and discuss its biocompatibility. Micro morphology in the surface of nano Ag/TiO2 coating bracket was detected by scanning electron microscope (SEM), and surface roughness of ordinary mental bracket, nano TiO2 coating bracket and nano Ag/TiO2 coating bracket were measure...

In the last two decades, considerable advances have been made in the investigation of nano-photonics in photonic crystals. Previous theoretical investigations of photon dynamics were carried out at zero temperature. Here, we investigate micro/nano cavity photonics in photonic crystals at finite temperature. Due to photonic-band-gap-induced localized long-lived photon dynamics, we discover that ...

Femtosecond fluorescence upconversion measurements are employed to elucidate the mechanism of ultrafast double proton transfer dynamics of BP(OH)2 inside molecular containers (cucurbit[7]uril (CB7) and β-cyclodextrin (β-CD)). Femtosecond up-converted signals of BP(OH)2 in water consist of growth followed by a long decay component (~650 ps). The appearance of the growth component (~35 ps) in the...

Dispersion characteristics of four types of superconducting nanowire single photon detectors, nano-cavity-array-(NCA-), nano-cavity-deflector-array-(NCDA-), nano-cavity-double-deflectorarray-(NCDDA-) and nano-cavity-trench-array-(NCTA-) integrated (A-SNSPD) devices were optimized in three periodicity intervals commensurate with half-, three-quarterand one surface plasmon polariton wavelength. T...

Silicon (Si) based integrated Photonic Crystal (PhC) cavities show great promise for biosensing applications, owing to their high Quality (Q) factor, low mode volume and compatibility with Complementary metal–oxide–semiconductor (CMOS) fabrication. We present the development of a new experimental technique to experimentally determine the sensing properties of PhC cavity mode. It makes use of a ...

We investigate the optomechanical effect on a single nano-particle inside an optical cavity, by deriving forces acting cavity from quantum theory. obtain steady state of system and found that force contains three terms associated with gradient force, back-action resulting intra-cavity photon energy change, as well reactive coupling between external field cavity. Moreover, we solve dynamical for...

We propose a scheme to efficiently couple a single quantum dot electron spin to an optical nano-cavity, which enables us to simultaneously benefit from a cavity as an efficient photonic interface, as well as to perform high fidelity (nearly 100%) spin initialization and manipulation achievable in bulk semiconductors. Moreover, the presence of the cavity speeds up the spin initialization process...
