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 μW*Hz−0.5), and the possibility to develop an internal absolute self-calibration estimated at 9.93 W*V−1 are reported. Advantages and drawbacks of this THz powermeter are discussed.< Réduire
