Photonics Spectra Preview - May 2023

Single-Photon Detection This article describes the technique of photon counting and its advantages and disadvantages compared to analog detection. Piatek will also discuss photon number resolution and the performance constraints it puts on the photodetector. To illustrate these concepts, he will describe representative applications relying on photon number resolution. Key Technologies: Single-photon detectors, though not expressly mentioned relevant techs include photomultiplier tubes, single-photon avalanche photodies (SPADs), silicon photomultipliers, and nanowire SPDs. Polymer Optics Where and why is plastic a better optical material than glass in imaging applications?” Weight and cost are part of that...
