| Abstract |
The recent progress in the device performance of the uni-traveling-carrier photodiode (UTC-PD) is described. The UTC-PD utilizes only electrons as the active carriers, and this unique feature is the key to achieving excellent high-speed and high-output characteristics simultaneously. The achieved performance includes a record 3-dB bandwidth of 310 GHz, high-power photonic millimeter-wave generation with an output power of over +13 dBm at 100 GHz, high-output-voltage photoreceiver operation at bit rates of up to 80 Gbit/s, and demultiplexing operation at 200 Gbit/s using a monolithic PD-EAM optical gate. |

| Abstract |
The paper reviews the main aspects of nonequilibrium hot-electron phenomena in superconductors and various theoretical models developed to describe the hot-electron effect. We discuss implementation of the hot-electron avalanche mechanism in superconducting radiation sensors and present the most successful practical devices, such as terahertz mixers and direct intensity detectors, for far-infrared radiation. Our presentation also includes the novel approach to hot-electron quantum detection implemented in superconducting x-ray to optical photon counters. |
