A device that sorts photon states could lead to a basic component of an all-optical quantum computer. Read More »
High-resolution imaging arrays could be realized by using the same superconducting technology for both the signal-processing electronics and the single-photon detectors. Read More »
Experiments and numerical simulations indicate that randomly replacing a few nonmagnetic components with magnetic ones in a photonic alloy induces backscattering-free light propagation along its edge. Read More »
A method for freely adjusting the parameters of a loop of optical fiber enables the exploration of exotic topological phases of matter. Read More »
Measuring a photon’s angular momentum after it passes through optical devices teaches an algorithm to reconstruct the properties of the photon’s initial quantum state. Read More »
The demonstration of a device that can triple the number of photons in a microwave signal is a key step toward making a single-microwave-photon detector. Read More »
Light–matter interactions in certain one-dimensional photonic materials can bring light nearly to a standstill, an effect that researchers show requires consideration of long-range interactions between the material’s components. Read More »
By using a pair of offset beams, researchers are able to generate femtosecond UV pulses that can be aimed directly into a target as a spectroscopic probe. Read More »
Using a metallic grating and infrared light, researchers have uncovered a light–matter coupling regime where the local coupling strength can be 3.5 times higher than the global average for the material. Read More »
A flower-petal pattern of light could induce electrical currents in a wider array of crystalline materials. Read More »
