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 (<25μW·Hz0.5), and the possibility to develop an internal absolute self-calibration estimated at 9.93W·V1 are reported. Advantages and drawbacks of this THz powermeter are discussed.
