<ul><li>Researchers have developed a tiny photonic-chip-based traveling-wave parametric amplifier (TWPA) that can boost light signals over a wider range of wavelengths.</li><li>Traditional fiber amplifiers, such as erbium-doped fiber amplifiers (EDFAs), have limitations in the range of light wavelengths they can amplify.</li><li>The TWPA, built using gallium phosphide-on-silicon dioxide technology, can amplify signals across 140 nanometers of bandwidth, which is three times wider than standard fiber amplifiers.</li><li>The compact chip-based amplifier can achieve up to 35dB of gain, making it valuable for internet, data centers, self-driving cars, and scientific instruments.</li></ul>
