Every time a smartphone snaps a photo, millions of tiny light detectors capture the scene and then ferry all that raw data ...

Figures of merit for single-photon detectors. The most widely quoted figure of merit for photodetectors is the noise equivalent power (NEP)24, and this has proved useful for optical power measurements ...

There is keen interest in extending the use of laser diodes beyond traditional low-power devices. Now the techniques needed to increase the achievable output power have become available. Laser diodes ...

Abstract: We introduce a novel configurable model of single photon avalanche diodes (SPAD) array photodetectors with intelligent control and active quenching, where individual components can be ...

Think about how easily you recognize a friend in a dimly lit room. Your eyes capture light, while your brain filters out background noise, retrieves stored visual information, and processes the image ...

Abstract: An ultra-wide band (UWB) antenna employing spoof surface plasmon polariton principles is introduced, offering tunable single- and dual-band rejection. Inserting slot resonators into the SSPP ...

- Set up a single unit cell with Bloch BCs in z, periodic in x/y. - Inject a broadband Gaussian pulse to excite all modes at once. - Wait for the non-resonant (non-propagating) transient to die away; ...
