Compact THz Laser Produces 120 Frequencies — With Room to Shrink
Researchers at Harvard have taken a step toward bringing terahertz frequencies out of their hard-to-reach region of the electromagnetic spectrum and into everyday applications. A team demonstrated a terahertz laser that is compact, operates at room temperature, and can produce 120 individual frequencies spanning the 0.25- to 1.3-THz range, far broader than previous terahertz sources.

Photon Counting for Low-Light Applications: SiPM, SPAD, SNSPD, PMT, TES, and Photon-Resolving Camera Technologies
Wed, Feb 16, 2022 1:00 PM - 2:00 PM EST
This webinar overviews six types of single-photon photodetectors for low-light conditions: photomultiplier tubes (PMTs), single-photon avalanche photodiodes (SPADs), silicon photomultipliers (SiPMs), superconducting nanowire single-photon detectors (SNSPDs), superconducting transition edge sensor (TES), and photon-resolving cameras. All of these detector technologies are becoming more popular as developers and suppliers aim toward satisfying the increasing demand for ‘modern’ photonic applications, including quantum computing, lidar, dark matter detection, and more. Presented by Hamamatsu Corporation.
