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,

Numerical Analysis of AgInSe2‐Based Thin‐Film Solar Cells Towards High Efficiency

Nano Select, EarlyView.
In this work, SCAPS‐1D is used to numerically explore AgInSe2‐based thin‐film solar cells. Using CuS, WSe2, and AlSb as back surface field (BSF) layers with a CdS window improves carrier separation and built‐in potential. AgInSe2's promise for high‐performance, stable, and environmentally friendly solar applications is demonstrated by the optimised CdS/
