۱۱٬۷۶۱ نتیجهCandidates for a possible third-generation gravitational wave detector: comparison of ring- Sagnac and sloshing-Sagnac speedmeter interferometers
Speedmeters are known to be quantum non-demolition devices and, by potentially providing sensitivity beyond the standard quantum limit, become interesting for third generation gravitational wave detectors. Here we introduce a new configuration, the sloshing-Sagnac interferometer,
Comparative Sensitivities of Gravitational Wave Detectors based on Atom Interferometers and Light Interferometers
iNe consider a class of proposed gravitational wave detectors based on multiple atomic interferometers separated by large baselines and referenced by common laser systems. We compute the sensitivity limits of these detectors due to intrinsic phase noise of the light sources, non-
Realization of an SU(1,1) Interferometer with Spinor Bose-Einstein Condensates
An SU(1,1) interferometer is obtained from a Mach-Zehnder interferometer by replacing both its beam splitters with parametric amplifiers. These new beam splitters are characterized by a non-linear response to a strong coherent pump beam and produce entangled photon pairs in its s
An Integrated Heterodyne Interferometer with on-chip Detectors and Modulators
The application of CMOS processing techniques developed in the microelectronics world to that of silicon photonics has been the catalyst for the rapid proliferation of smaller, higher performance, and more densely integrated photonic devices that are rapidly advancing the field w
Experimental investigation of a control scheme for a zero-detuning resonant sideband extraction interferometer for next-generation gravitational-wave detectors
Some next-generation gravitational-wave detectors, such as the American Advanced LIGO project and the Japanese LCGT project, plan to use power recycled resonant sideband extraction (RSE) interferometers for their interferometer’s optical configuration. A power recycled zero-detun
Quantum Optics and Photonics 1. Single-zone Atom Interferometer : Experimental Observation
In a typical atomic interferometer, the atomic wavepacket is split first by what can be considered effectively as an atomic beamsplitter. The split components are then redirected towards each other by atomic mirrors. Finally, the converging components are recombined by another at
Performance Analysis of a Space-Based Multiple-Telescope Nulling Interferometer for DARWIN
The European Space Agency’s infrared space interferometer DARWIN is dedicated to the investigation of Earth-like extrasolar planets orbiting bright stars. A multi-aperture interferometer fed by free-flying telescopes allows spectroscopic analysis of the weak planet signal which c
ASEPS-O Testbed Interferometer
The ASEPS-O Testbed Interferometer is a long-baseline infrared interferometer optimized for high-accuracy narrow-angle astrometry. It is being constructed by JPL for NASA as a testbed for the future Keck Interferometer to demonstrate the technology for the astrometric detection o
Microwave Interferometers for Non - Contact Vibration Measurements on Large Structures
This paper describes a non-contact vibration measuring system that is based on a microwave interferometer similar to those used to detect the presence of people in monitored areas. Displacement response of a target surface on the structure relative to the interferometer is measur
Optimizing interferometer experiments for CMB B mode measurement
The sensitivity of interferometers with linear polarizers to the CMB E and B mode are variant under the rotation of the polarizer frame, while interferometer with circular polarizers are equally sensitive to E and B mode. We present analytically and numerically that the diagonal
