Pulse Generation by On‐Chip Dispersion Compensation at 8 µm Wavelength
Laser &Photonics Reviews, EarlyView.This work demonstrates on‐chip pulse generation at 8 μm$\mathrm{\mu}\mathrm{m}$ using chirped Bragg gratings in SiGe graded‐index photonic circuits to compensate the quadratic phase of quantum cascade laser frequency combs. With this approach pulses as short as 1.39 ps were produced, close to the transform limit, representing a key step toward compact,

Time‐Stretched Interferometric LiDAR with Dispersive Wavenumber‐to‐Time Range Encoding
Laser &Photonics Reviews, EarlyView.We present a time‐stretched interferometric LiDAR that directly encodes distance into time‐domain interference signals. Operating at 5 MHz with only millimeter‐level coherence length, the system measures up to 12 m with centimeter precision and resolution, achieving high‐speed 3D imaging and dynamic target detection without FFT processing or long ...

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.
