Strongly enhanced light emission at wavelengths between 1.3 and 1.6 ␮m is reported at room temperature in silicon photonic crystal ͑PhC͒ nanocavities with optimized out-coupling efficiency. Sharp peaks corresponding to the resonant modes of PhC nanocavities dominate the broad sub-bandgap emission from optically active defects in the crystalline Si membrane.(More)
BACKGROUND Emergence of polyantimicrobial resistant strains of hospital pathogens has presented a challenge in the provision of good quality in-patient care. Inappropriate use of antibiotics in the hospital is largely responsible for this catastrophe. Bacteriological surveillance of the cases of nosocomial infections is crucial for framing an evidence-based(More)
With the explosive growth of the Internet and all of its computing hardware/software technologies it is possible to conceive Robots Teleoperated over the Internet to be the next revolution in the world of Robotics. The internet based teleoperationsfind great utility in applications that are dangerous, hostile, and inaccessible to humans and areas of work(More)
We present experimental measurements on silicon-on-insulator (SOI) photonic crystal slabs with an active layer containing Er<sup>3+</sup> ions-doped silicon nanoclusters (Si-nc), showing strong enhancement of 1.54 mum emission at room temperature. We provide a systematic theoretical analysis to interpret such results. In order to get further insight, we(More)
