Abstract

We describe a device consisting of a set of silicon plates to be employed for calibrating the linearity of amplitude/power measurements of terahertz systems and detectors. The device is used to test a time-domain spectrometer, a pyroelectric sensor, and a Golay cell. The results demonstrate that the linearity of amplitude/power measurement cannot be assumed but must be experimentally verified.
