Broadband Parametric Amplification in AlGaAs‐on‐Insulator Nanowaveguides

open access: yesLaser &Photonics Reviews, Volume 20, Issue 16, 21 August 2026.
Harnessing the exceptional nonlinearity of AlGaAs‐on‐insulator nanowaveguides, four‐wave‐mixing parametric amplification achieves a record net on‐chip gain of 56 dB and a gain bandwidth exceeding 415 nm at telecom wavelengths. These results establish AlGaAsOI as a powerful platform for compact, high‐performance integrated nonlinear optical ...
