  • Abstract
    We designed a new terahertz detector using a superconducting tunnel junction. The detector is composed of a small junction (~2 mum in diameter) coupled to a thin superconductor film with a large absorbing area (~200 mum square). The noise equivalent power (NEP) of the optimized detector is expected to be in the order of 10-18 W/radicHz.
