Highly Versatile Real‐Time Optical Noise Filtering Through Temporal Cloaking
Laser &Photonics Reviews, EarlyView.Conventional bandpass filtering strategies may be insufficient for recovering optical waveforms under extremely noisy conditions. We demonstrate a temporal‐cloaking denoising strategy enabled by the temporal Talbot effect, which concentrates the coherent signal of interest into short temporal slots while broadband noise remains temporally spread.

Broadband Parametric Amplification in AlGaAs‐on‐Insulator Nanowaveguides
Laser &Photonics Reviews, EarlyView.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 ...
