Germanium‐Based Mid‐Infrared Integrated Photonics

Laser &Photonics Reviews, EarlyView.
The mid‐infrared (mid‐IR) spectral range is a part of the electromagnetic spectrum in which most of the molecules have vibrational and rotational resonances. Photonics integration in this wavelength range have thus seen a burst of interest in the recent years, mainly driven by applications related with the detection of chemical and biological ...

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 ...

A Solventless Melt Route to Polymer/Mixed‐Metal Sulfide Nanocomposites: Case Study on NiCo2S4/PVP

Journal of Polymer Science, EarlyView.
Solvent‐free thermolysis of metal (Ni, Co)‐ xanthate precursors in PVP enables the in situ formation of NiCo2S4 nanoparticles embedded within the polymer matrix. ABSTRACT Polymer‐inorganic nanocomposites are commonly prepared using solution‐based approaches that rely on solvents, often toxic or costly, and multi‐step processing, which can limit ...
