Compared with other typical terahertz (THz) detectors, the quantum-well photodetector (QWP) has the advantages of high detection sensitivity, fast response, mature fabrication, small size, and easy integration. When applied to the photodetectors, this theory means that when light is absorbed by the thinner device and MoS 2 electrons jump into an excited state, they leave holes -- basically positions left empty by electrons that absorbed enough energy to jump to a higher energy status, researchers said. We demonstrate an all-silicon micro-ring resonant photodetector with a responsivity of 0.23 A/W and dark current <100nA capable of detecting 112 Gb/s PAM4 signal with an eye closure penalty of <1.0 dB.
