The premature edge breakdown of the avalanche photon diode (APD) is an important factor that affects the single photon counting of the avalanche diode [4]. Guard ring is an effective method to prevent ...

Abstract: We have proposed a modified structure called the “charge focusing” design of a single-photon avalanche diode, based on our previous work using TSMC's 0.18 μm HV CMOS technology. We have ...

Researchers have designed a single-photon time-of-flight LiDAR system that can acquire a high-resolution 3D image of an object or scene up to 1 kilometer away. The new system could help enhance ...

The start-up's products have a range of sensors with layers of advanced computation to extract information from images ...

Summary Singular Photonics, a University of Edinburgh spinout, has developed next-gen image sensors using single photon av ...

In the realm of quantum information distribution, sending a signal from point A to point B is like a baseball pitcher ...

This new device generates spin-orbit photonic qudits, which encode information in light by manipulating its shape (orbital angular momentum) and twist (polarization). Instead of encoding information ...

23, 2025 /PRNewswire/ -- Singular Photonics emerged from stealth mode today, launching a new generation of image sensors based on single photon avalanche diodes (SPADs). A spin-out from the ...
