Scientists at KAIST have fabricated a laser system that generates highly interactive quantum particles at room temperature.
Their findings, published in the journal Nature Photonics, could lead to a single microcavity laser system that requires lower threshold energy as its energy loss increases.
The system, developed by KAIST physicist Yong-Hoon Cho and colleagues, involves shining light through a single hexagonal-shaped microcavity treated with a loss-modulated silicon nitride substrate. [Read more…] about Quantum laser turns energy loss into gain?
