The precise control of micro-mechanical oscillators is fundamental to many contemporary technologies, from sensing and timing to radiofrequency filters in smartphones. Over the past decade, quantum control of mechanical systems ...
Peripheral photoinhibition (PPI) direct laser writing (DLW) is a lithography technique used to fabricate intricate 3D nanostructures that are widely employed in photonics and electronics. PPI-DLW uses two beams, one to excite ...
A new type of active pixel sensor that uses a novel two-dimensional material may both enable ultra-sharp cellphone photos and create a new class of extremely energy-efficient Internet of Things (IoT) sensors, according to ...
In metasurfaces, surface lattice resonances (SLRs) and bound state in the continuum (BIC) are two convenient approaches for achieving high quality factors (Q-factors).
Lithium niobite (LN) with an ultra-wide optical transparent window has shown excellent nonlinear, electro-optic, acoustic-optic, piezoelectric, thermoelectric and photorefractive effects. It is an excellent platform for realizing ...
Until recently, it was widely believed among physicists that it was impossible to compress light below the so-called diffraction limit (see below), except when using metal nanoparticles, which unfortunately also absorb light. ...
Australian researchers have engineered a quantum box for polaritons in a two-dimensional material, achieving large polariton densities and a partially "coherent" quantum state.
If you've ever tried to carry on a conversation in a noisy room, you'll be able to relate to the scientists and engineers trying to "hear" the signals from experimental quantum computing devices called qubits. These basic ...
Whether looking out into space or peering deep into the microscopic realm, there is always more to see. In the case of solids, there is a world of atoms and particles teeming with activity that ultimately leads to useful ...
Microcombs have widely differing application areas—they can help us discover planets outside our solar system as well as track diseases in our bodies. New research results at Chalmers University of Technology, Sweden, now ...
