**Tiny New Optical Amplifier Boosts Light by 100x**

By Sara Zaske, Stanford University - Published on 28 February 2026

A new Stanford-designed optical amplifier uses energy recycling in a resonator to deliver strong, low-noise amplification with far less power. Light underpins much of today’s technology, from televisions and satellites to the fiber optic cables that transmit internet data across continents. A team of Stanford physicists has now developed a way to push light-based systems [...]
