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 کاملTunable single-photon frequency conversion in a Sagnac interferometer.
Quantum information carriers like photons might be manipulated, stored and transmitted in different quantum systems. It is important to integrate those systems efficiently. The capability of converting photons from one wavelength to another wavelength is a key requirement for combining the photons in telecommunications band for quantum transmission and the photons in near-visible band for quant...
متن کاملSingle Mode Fiber Optic Sagnac Interferometer with Wireless Data Collection
Since the introduction of fiber optic gyroscope in the late 1970’s 1, the need for accurate inertial navigational instruments has driven the evolution of the device into complex open or closed loop designs manufactured with expensive polarization maintaining fibers and fused fiber optic elements. Our goal herein is to describe a novel fiber optic Sagnac interferometer design made with readily a...
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 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...
