Researchers have developed a new technique to better measure special "terahertz" light. This light travels in waves longer than the infrared light that is beyond what the human eye perceives. The new sampling technique preserves ...
Qubits are a basic building block for quantum computers, but they're also notoriously fragile—tricky to observe without erasing their information in the process. Now, new research from the University of Colorado Boulder ...
Traveling waves are commonly observed in biological and synthetic systems, and recent discoveries have shown how silver colloids form traveling motion waves in hydrogen peroxide under UV light. In a new report now published ...
An international team of laser physicists of the attoworld team at LMU and the Max Planck Institute of Quantum Optics has achieved unprecedented control over light pulses in the mid-infrared wavelength range.
Traditional acousto-optic (AO) devices based on bulk crystal materials have weak energy confinement abilities for both photons and phonons, leading to a low AO interaction strength. Compared with bulk materials, photonic ...
Photonic integrated circuits (PICs) use photons as information carriers and are expected to solve the bottleneck problems of microelectronic chips in terms of speed, power consumption and integration density with their advantages ...
A new publication in Opto-Electronic Advances overviews dynamic metasurfaces and metadevices empowered by graphene.
Compact, CMOS compatible on-chip photon sources have attracted much attention to the scientific community and the semiconductor industry. As the transistor's feature size is continuously scaling down, the integration density ...
A collaboration with Harvard University has led to the development of a new-generation electro-optic modulator that could stamp out its bulky predecessor through the creation of a smaller, stronger, cooler, faster and cost-effective ...
For all the recent advances in integrated lithium niobate photonic circuits—from frequency combs to frequency converters and modulators—one big component has remained frustratingly difficult to integrate: lasers.
