Simultaneous ponderomotive squeezing of light by two mechanical modes in an optomechanical system
Peyman Malekzadeh, Emil Zeuthen, Eric Langman +2
We experimentally demonstrate a source of squeezed light featuring simultaneous ponderomotive squeezing from two mechanical modes of an optomechanical system. We use ultra-coherent…
A soft-clamped topological waveguide for phonons
Xiang Xi, Ilia Chernobrovkin, Jan Košata +5
Topological insulators were originally discovered for electron waves in condensed matter systems. Recently this concept has been transferred to bosonic systems such as photons and…
Enhancing Membrane-Based Scanning Force Microscopy Through an Optical Cavity
Thomas Gisler, David Hälg, Vincent Dumont +6
The new generation of strained silicon nitride resonators harbors great promise for scanning force microscopy, especially when combined with the extensive toolbox of cavity optomec…
Strong Thermomechanical Noise Squeezing Stabilized by Feedback
Aida Mashaal, Lucio Stefan, Andrea Ranfagni +5
Squeezing the quadrature noise of a harmonic oscillator used as a sensor can enhance its sensitivity in certain measurment schemes. The canonical approach, based on parametric modu…
A Long-lived and Efficient Optomechanical Memory for Light
Mads Bjerregaard Kristensen, Nenad Kralj, Eric Langman +1
We demonstrate a memory for light based on optomechanically induced transparency. We achieve a long storage time by leveraging the ultra-low dissipation of a soft-clamped mechanica…
Membrane-in-the-middle optomechanics with a soft-clamped membrane at milliKelvin temperatures
Eric Planz, Xiang Xi, Thibault Capelle +2
Soft-clamped silicon nitride membrane resonators reach coherence times tau in excess of 100 ms at milliKelvin bath temperatures. However, harnessing strong optomechanical coupling…
Laser cooling a membrane-in-the-middle system close to the quantum ground state from room temperature
Sampo A. Saarinen, Nenad Kralj, Eric C. Langman +2
Many protocols in quantum science and technology require initializing a system in a pure quantum state. In the context of the motional state of massive resonators, this enables stu…
Strong parametric coupling between two ultra-coherent membrane modes
David Hälg, Thomas Gisler, Eric C. Langman +5
We demonstrate parametric coupling between two modes of a silicon nitride membrane. We achieve the coupling by applying an oscillating voltage to a sharp metal tip that approaches…
Ground State Cooling of an Ultracoherent Electromechanical System
Yannick Seis, Thibault Capelle, Eric Langman +3
Cavity electromechanics relies on parametric coupling between microwave and mechanical modes to manipulate the mechanical quantum state, and provide a coherent interface between di…
Modelling and observation of nonlinear damping in dissipation-diluted nanomechanical resonators
Letizia Catalini, Massimiliano Rossi, Eric C. Langman +1
Dissipation dilution enables extremely low linear loss in stressed, high-aspect ratio nanomechanical resonators, such as strings or membranes. Here, we report on the observation an…
Membrane-based scanning force microscopy
David Hälg, Thomas Gisler, Yeghishe Tsaturyan +11
We report the development of a scanning force microscope based on an ultra-sensitive silicon nitride membrane transducer. Our development is made possible by inverting the standard…
Purification of a single photon nonlinearity
H. Snijders, J. A. Frey, J. Norman +6
We show that the lifetime-reduced fidelity of a semiconductor quantum dot-cavity single photon nonlinearity can be restored by polarization pre- and postselection. This is realized…
A titanium-nitride near-infrared kinetic inductance photon-counting detector and its anomalous electrodynamics
J. Gao, M. R. Visser, M. O. Sandberg +10
We demonstrate single-photon counting at 1550 nm with titanium-nitride (TiN) microwave kinetic inductance detectors. Energy resolution of 0.4 eV and arrival-time resolution of 1.2…
A superconducting focal plane array for ultraviolet, optical, and near-infrared astrophysics
Benjamin A. Mazin, Bruce Bumble, Seth R. Meeker +3
Microwave Kinetic Inductance Detectors, or MKIDs, have proven to be a powerful cryogenic detector technology due to their sensitivity and the ease with which they can be multiplexe…
