Scientists from Leipzig University and Nanyang Technological University showed that, contrary to popular scientific belief, light can generate electrical currents in a material even if the material...

A team at Nanyang Technological University (NTU) developed an electrically pumped, topological, bulk quantum cascade laser (QCL) that operates in the terahertz (THz) frequency range. The THz QCL is...

According to prevailing wisdom, long-distance quantum computing requires the ability to entangle qubits made from matter, in which information is stored and manipulated locally, with photonic qubits...

LCOS-SLMs are liquid crystal on silicon-based spatial light modulators that manipulate light by way of electrically controlling optical amplitude, phase, and polarization. SLMs may be used to...

In general, there are three common approaches to reducing mechanical excitation of photonic systems. The first is identifying the sources of vibration and implementing ways to eliminate or reduce...
