Anticaustics in a Fabry-Perot interferometer
L. L. Sanchez-Soto, J. J. Monzon, G. Leuchs
We address the response of a Fabry-Perot interferometer to a monochromatic point source. We calculate the anticaustics (that is, the virtual wavefronts of null path difference) res…
Imaging below the camera noise floor with a homodyne microscope
Osian Wolley, Simon Mekhail, Paul-Antoine Moreau +4
We present a wide-field homodyne imaging system capable of recovering intensity and phase images of an object from a single camera frame at an illumination intensity significantly…
Microsphere kinematics from the polarization of tightly focused nonseparable light
Stefan Berg-Johansen, Martin Neugebauer, Andrea Aiello +3
Recently, it was shown that vector beams can be utilized for fast kinematic sensing via measurements of their global polarization state [Optica 2(10), 864 (2015)]. The method relie…
Nonlinear power dependence of the spectral properties of an optical parametric oscillator below threshold in the quantum regime
Golnoush Shafiee, Dmitry V. Strekalov, Alexander Otterpohl +6
Photon pairs and heralded single photons, obtained from cavity-assisted parametric down-conversion (PDC), play an important role in quantum communications and technology. This moti…
Compensation-Free High-Capacity Free-Space Optical Communication Using Turbulence-Resilient Vector Beams
Ziyi Zhu, Molly Janasik, Alexander Fyffe +7
Free-space optical communication is a promising means to establish versatile, secure and high-bandwidth communication for many critical point-to-point applications. While the spati…
Quantum-limited measurements of intensity noise levels in Yb-doped fiber amplifiers
Alexandra Popp, Victor Distler, Kevin Jaksch +7
We investigate the frequency-resolved intensity noise spectrum of an Yb-doped fiber amplifier down to the fundamental limit of quantum noise. We focus on the kHz and low MHz freque…
