Stimulated Brillouin scattering (SBS), Brillouin lasing and SBS-coupled four-wave mixing were observed in an ultrahigh Q whispering gallery mode microbottle resonator fabricated on a single mode optical fiber.
We perform an entanglement distillation protocol on pure and mixed states using optical metamaterials composed of gold nano-antennas and measure the density matrices by quantum-state tomography. The fidelity is improved from 0.85 to 0.97.
Hybrid wishpering-gallery-mode resonators were made by depositing a ploycrystalline lihtiiim noibate film onto silica resonators. Efficient coupling with tapered fiber and all-optical modulation were realized in these resonators.
Optical signals are increasingly used to transfer and process information, because of their high speed, bandwidth, and propagation distances in transparent optical networks. However, the miniaturization of photonic devices faces a hard block: the diffraction limit. One proposed means to go beyond this limit is to use surface plasmons polaritons (SPPs), charge density waves at the interface between...
A fiber taper-based method for label-free Raman sensing is presented, which exploits the interaction between adsorbed specimen and the exposed evanescence tail of guided pump light. Chemical specificity and detection of microsphere specimens with diameters as small as 1 \(\mu \) m are shown. To improve the sensitivity, we further propose resonator-enhanced Raman spectroscopy by taking advantage of...
Future manned space missions to the Moon or to Mars will require a vehicle for transporting astronauts in a controlled and protected environment and in relative comfort during surface traverses of these planetary bodies. The vehicle that will be needed is a pressurized rover which provides the astronauts a habitat, a refuge and a research laboratory/workshop. RAMA (Rover for Advanced Mission Applications)...
In this work, a new random number generator circuit using continuous-time chaos is described. The circuit is based on the classical dual oscillator sampling technique. In the classical approaches, the jittered oscillations used in this technique are obtained using a physical noise. In this work, we propose to use continuous-time chaos to generate these oscillations. The required chaotic signal is...
This paper discusses the analogies between habitable terrestrial structures in extreme conditions and Lunar habitats, which are in an even more unforgiving environment. Terrestrial structures like manned military or utility machines (submarines, zeppelins...) and facilities functioning in extreme environments (oilrigs, polar outposts, underwater facilities...) are good examples to be studied in order...
