Sagnac interferometer for gravitational-wave detection.
We have investigated a zero-area Sagnac interferometer as a broad band gravitational-wave detector. Frequency response measurements of a laboratory-scale interferometer are in excellent agreement with theory. The measured contrast ratio, 0.996, is insensitive to induced birefringence, laser-frequency variation, arm imbalance, and dc mirror displacement. A near shot-noise-limited phase sensitivi...
متن کاملUltrafast gating using a nonlinear Sagnac interferometer
Ultrafast gating is a powerful technique for applications such as time resolved spectroscopy [ 1-3 ], imaging through scattering media [4-7 ], or nonlinear optics [ 8 ]. Several methods have been used, each of which has its own limitations. The Kerr shutter [ 3 ] is extremely fast (femtosecond) but requires high peak power lasers. It has a maximum transmission of approximately 10 percent, and i...
متن کاملSingle-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 کاملPolarization Sagnac interferometer with postmodulation for gravitational-wave detection.
We describe a polarization Sagnac interferometer with an in-loop half-wave plate that allows signal detection at the reciprocal port of the beam splitter while maintaining the ability to detect the signal at a dark fringe. Postmodulation and balanced heterodyne detection are used to recover the signal. This topology is simple to control because of its common-path characteristics and its colline...
متن کاملContinuous phase amplification with a Sagnac interferometer
We describe a phase-amplification technique using a Sagnac interferometer. We monitor the relative phase between two paths of a precisely misaligned interferometer by measuring the average position of a split-Gaussian mode in the dark port. Although we monitor only the dark port, we show that the signal varies linearly with phase and that we can obtain similar sensitivity to balanced homodyne d...
