Abstract

Coupling optical and thermal properties of a terahertz (THz) thermal converter based on the Seebeck effect provides an unsupplied room-temperature measuring device dedicated to THz power metrology. Performance characteristics such as broadband response (0–30 THz), high sensitivity ($<25\mathrm{\mu W}·{\mathrm{Hz}}^{-0.5}$), and the possibility to develop an internal absolute self-calibration estimated at $9.93\mathrm{W}·{\mathrm{V}}^{-1}$ are reported. Advantages and drawbacks of this THz powermeter are discussed.
