Micro‐Transfer Printed Continuous‐Wave and Mode‐Locked Laser Integration at 800 nm on a Silicon Nitride Platform

Laser &Photonics Reviews, EarlyView.
A heterogeneous III‐V/SiN platform for lasers at 800 nm is realized using the micro‐transfer printing method. Efficient GaAs gain sections are directly butt‐coupled to SiN waveguides, enabling continuous‐wave and mode‐locked extended‐cavity lasers. The mode‐locked lasers generate highly stable pulse trains with repetition rates up to 9.2 GHz and a ...

Long‐Range Exciton Energy Transfer in Two‐Dimensional Materials

Laser &Photonics Reviews, EarlyView.
This review highlights recent advances in long‐range exciton energy transfer within planar 2D‐material architectures. It emphasizes the emergence of self‐hybridized excitonpolaritons, exciton coupling to surface plasmon polaritons and plasmonic lattices, and the role of dipoledipole transfer pathways in enabling efficient nanoscale energy transport ...

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 ...

Non‐Uniform Programmable Photonic Waveguide Meshes

Laser &Photonics Reviews, EarlyView.
Integrating defect cells into uniform hexagonal waveguide meshes overcomes the fundamental spectral and temporal limitations of programmable photonics. By leveraging the Vernier effect through non‐uniform coupled cavities, this architecture achieves a tenfold increase in free spectral range and ultra‐fast sampling times, paving the way for next ...
