We propose in this work an original nanobeam cavity geometry for the hybrid integration of active materials in silicon photonics. The key point of this structure is to use Bragg mirrors exploiting a dielectric dispersion band, to form a field-confining cavity core relying on an air dispersion band. The resulting situation opens the way for a gentle confinement of the electromagnetic field in the low-index...
In this paper, we present an experimental study, validated by two different approaches, of the influence of the top cladding refractive index on the transmission and slow light properties of dispersion engineered silicon slot photonic crystal waveguides. We demonstrate that even though the operation wavelength is very sensitive to refractive index changes, the structures remain, nevertheless, robust...
Stock market is complex and volatile, the stock price trends is not only related to the stock price history, but also have a certain correlation with the national policy, the economic environment and the unexpected events of company. Most of the existing stock market prediction methods are only based on the history of stock price and neglect the influence of public sentiment. Nowadays, Social networks...
Properties of non-freestanding silicon slot photonic crystal cavities for application to sensing are investigated by probing their resonance wavelength tuning as a function of covering material index. Sensitivities of 225 nm/RIU are obtained with Q around 30,000 and cavity mode volumes ∼ V=0.03(λ/n)3
Method of artillery effectiveness valuation was introduced. According to the theory of grey systems, the patterns of alternative schemes are formed with the fourteen performance indices, which reflect the artillery effectiveness best, and the standard mode of these index series is derived according to the grey target theory. The weighting of every indices was determined by Shannon information entropy,...
