New cold atom source lays groundwork for portable quantum devices

Although quantum technology has proven valuable for highly precise timekeeping, making these technologies practical for use in a variety of environments is still a key challenge. In an important step toward portable quantum ...

A disposable living laser printed on chip for drug screening

Scientists have created a new way to monitor subtle drug interactions between bacteria and antibiotics. By using a common office inkjet printer, researchers from NTU Singapore and China developed a disposable living laser ...

Advance in 'optical tweezers' to boost biomedical research

Much like the Jedis in Star Wars use the Force to control objects from a distance, scientists can use light or optical force to move very small particles. The inventors of this ground-breaking laser technology, known as "optical ...

Increasing optical data transmission speed

Pulsed lasers repeatedly emit light for a short period of time as if blinking. They have the advantage of focusing more energy than a continuous wave laser, whose intensity is kept unchanged over time. If digital signals ...

Physicists make electrical nanolasers even smaller

Researchers from the Moscow Institute of Physics and Technology and King's College London cleared the obstacle that had prevented the creation of electrically driven nanolasers for integrated circuits. The approach, reported ...
