摘要：

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 mu W.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. (C) 2013 Optical Society of America
