Single-photon Sagnac interferometer
We present the first experimental demonstration of the optical Sagnac effect at the single-photon level. Using a high quality guided-wave heralded singlephoton source at 1550 nm and a fibre optics setup, we obtain an interference pattern with net visibilities up to (99.2 ± 0.4%). On the basis of this high visibility and the compactness of the setup, the interest of such a system for fibre optic...
متن کاملGuided magnonic Michelson interferometer
Magnonics is an emerging field with potential applications in classical and quantum information processing. Freely propagating magnons in two-dimensional media are subject to dispersion, which limits their effective range and utility as information carriers. We show the design of a confining magnonic waveguide created by two surface current carrying wires placed above a spin-sheet, which can be...
متن کاملTwo-wavelength holographic interferometer.
In optical testing, when the wave-front error of a test optic is much larger than the wavelength of visible light, it may be difficult to analyze the closely spaced interference fringes in the interferogram. The use of a less-sensitive testing technique or a long-wavelength interferometer would be preferred for this purpose. In addition, when the optic is to be tested in transmission, the wavel...
متن کاملFabry - Perot Interferometer Prototype
A new Fabry-Perot Interferometer has been developed for the ADAHELI ADvanced Astronomy for HELIophysics solar satellite mission at the “Tor Vergata” University Solar Physics Laboratory. Fabry-Perot narrow filters are of great interest for the study of extended astronomical sources, such as the solar photosphere and chromosphere. The prototype instrument provides a high throughput that allows fo...
متن کاملBroad-Band Difference Interferometer
Thanks to researches and the development of integrated optics devices for optical applications in the telecommunications, relatively cheap sources and detectors of optical radiation that can be used in the design of planar optical sensors [1, 2]. One of the commonly used sensor systems is the differential interferometer, based on planar waveguides [3]. In the analyzed system propagates a mode f...
