In future high-tech industries, such as high-speed optical computing for massive AI, quantum cryptographic communication, and ultra-high-resolution augmented reality (AR) displays, nanolasers—which process information using light—are gaining significant attention as core components for next-generation semiconductors.
A research team has proposed a new manufacturing technology capable of high-density placement of nanolasers on semiconductor chips, which process information in spaces thinner than a human hair.
A joint research team led by Professor Ji Tae Kim from the Department of Mechanical Engineering and Professor Junsuk Rho from POSTECH, has developed an ultra-fine 3D printing technology capable of creating “vertical nanolasers,” a key component for ultra-high-density optical integrated circuits.

A team of physicists from the University of Amsterdam’s Institute of Physics has 3D-printed a Christmas tree made entirely of ice. Researchers Menno Demmenie, Stefan Kooij and Daniel Bonn used no freezing technology or refrigeration equipment—just water and a vacuum. In time-lapse videos, you can see how the Christmas tree is printed and how it melts again when the vacuum pump is turned off. The work is published on the arXiv preprint server.
The secret of the tree lies in so-called evaporative cooling. This is the same principle mammals use to regulate their body temperature.
In a low-pressure vacuum chamber, water evaporates rapidly at room temperature. As each water molecule evaporates, it takes with it a small amount of heat, causing the remaining water to become increasingly colder, eventually cooling to below 0°C. At that point, the water is still liquid, but supercooled. As soon as the ultra-thin stream (about as thin as a human hair: 16 micrometers) hits the already formed layer of ice, it freezes instantly.
