Second order non-linear optical features of anchor attached azophenylcarbazole based derivative 9-(2,3-epoxy)propyl-2-(2,3-epoxy)propoxy-3-(4-nitrophenyl)azo-9H-carbazole dispersed in polycarbonate was investigated. Using all-optical poling technique writing and reading kinetics of second order susceptibility gratings were measured. Theoretical modelling of the experimental results revealed one…

We demonstrate subwavelength grating devices in silicon-on-insulator including Bragg gratings, racetrack resonators, and optical delay lines. The Bragg grating filter has a 3 dB bandwidth of 0.5 nm and a reflectivity of 90%; the racetrack resonator has a 3 dB…

Connectivity services now provide a competitive edge in the automotive industry. As the range of automotive applications grows, better policy-based control is needed. This paper proposes a Context-Aware Policy System (CAPS) for the motoring industry, which enables offering advanced communication-based…

Multiview representations reveal the fundamental attributes of the studied instances from different perspectives. Some common perspectives are reviewed by multiple views simultaneously, while some specific ones are reflected by individual views. That is, there are two kinds of properties embedded…
