First integrated laser on lithium niobate chip

“Research paves the way for high-powered telecommunication systems 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. Long haul telecommunication …

The first topological acoustic transistor

“Sound waves may pave the way for topological electronic transistors Topological materials move electrons along their surface and edges without any loss, making them promising materials for dissipationless, high-efficiency electronics. Researchers are especially interested in using these materials as transistors …

Exotic quantum particles — less magnetic field required

“Research paves the way for future quantum devices and applications Exotic quantum particles and phenomena are like the world’s most daring elite athletes. Like the free solo climbers who scale impossibly steep cliff faces without a rope or harness …

Shifting colors for on-chip photonics

“The ability to precisely control and change properties of a photon, including polarization, position in space, and arrival time, gave rise to a wide range of communication technologies we use today, including the Internet. The next generation of photonic technologies …

Simple silicon coating solves long-standing optical challenge

“New approach expands the application of powerful, ultrafast laser pulses. Quick bursts of laser light, lasting less than a trillionth of a second, are used in a range of applications today. These ultrashort laser pulses have allowed scientists to observe …

Shape-shifting materials with infinite possibilities

“Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a shape-shifting material that can take and hold any possible shape, paving the way for a new type of multifunctional material that could be …

Bridging optics and electronics

“New spatial light modulator marries optical and electronic realms Spatial light modulators are common optical components found in everything from home theater projectors to cutting-edge laser imaging and optical computing. These components can control various aspects of a light, such …

Harnessing the dark side

“Optical singularities could be used for a wide range of applications from super resolution imaging to optical trapping When we think about singularities, we tend to think of massive black holes in faraway galaxies or a distant future with runaway …

Harvard-led physicists take big step in race to quantum computing

“Team develops simulator with 256 qubits, largest of its kind ever created A team of physicists from the Harvard-MIT Center for Ultracold Atoms and other universities has developed a special type of quantum computer known as a programmable quantum …

Pop-up coffee table — no assembly required

“Kiriform structures harness buckling for stable, deployable structures Deployable structures — objects that transition from a compact state to an expanded one — are used everywhere from backyards to Mars. But as anyone who has ever struggled to open an uncooperative folding …
