Perovskite‐based time‐domain signal‐balancing LiDAR sensor with centimeter depth resolution

InfoMat, EarlyView.
In this study, we present a monolithic high‐speed perovskite‐based photodetector capable of directly sensing the time delay between two light pulses with a temporal resolution of at least 170 ps. This outstanding time resolution is achieved through a signal‐balancing detection scheme that effectively overcomes the limitations of conventional ...

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 ...

A Linear‐to‐Linear Cross‐Polarization Conversion q‐BIC Metasurface for Transmission Mode Mid‐Infrared Spectral Filtering

Laser &Photonics Reviews, EarlyView.
Manipulating the ultranarrow linewidth spectral features of quasi bound states in the continuum is challenging. A metasurface supporting linear‐to‐linear cross‐polarization coupling efficiency surpassing 25% is proposed to address the issue. Less than 100 nm linewidth is achieved, enabling the device to be applied to wavelength‐selective polarization ...
