Optical phase modulators are key components in optical communication, sensing, and signal processing systems. All-optical modulators, which modulate the phase or intensity of a light signal by a control light beam, have attracted ...
Femtosecond pulsed lasers—which emit light in ultrafast bursts lasting a millionth of a billionth of a second—are powerful tools used in a range of applications from medicine and manufacturing, to sensing and precision ...
In recent years, global digitalization has seen unprecedented acceleration. Video streaming and video conferencing in home office and remote learning settings has resulted in a spike in residential broadband usage. Emerging ...
If you hold one wire mesh on top of another one and look through it, you'll see a larger pattern called a moiré pattern formed by the overlapping grids of the two meshes, which depends on their relative twisted angle. Scientists ...
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. ...
Albert Einstein, one of the most celebrated modern scientists, proposed the revolutionary theory of special relativity more than a century ago. This theory forms the basis of most of what we understand about the universe, ...
Using existing experimental and computational resources, a multi-institutional team has developed an effective method for measuring high-dimensional qudits encoded in quantum frequency combs, which are a type of photon source, ...
A research team led by Prof. Gao Xiaoming from the Hefei Institutes of Â鶹ÒùÔºical Science of the Chinese Academy of Sciences has developed a new spectrometer capable of remotely sensing atmospheric methane (CH4), water vapor ...
A new publication from Opto-Electronic Advances discusses spatiotemporal manipulation of femtosecond light pulses for on-chip devices.
