Paper Abstract

A highly sensitive fast room temperature FIR detector is proposed. The detector operation is based on intraband photoconductivity in semiconductors. It has a time resolution of 100 ps and operates in the spectral range from 50 to micrometers to 500 micrometers . Its sensitivity (at (lambda) equals 90 micrometers is 30 (mu) V/W without and 6 mV/W with a 300 MHz bandwidth amplifier) increases with wavelength as (lambda) 2. This is at least by two orders of magnitude higher than the sensitivities of fast pyroelectric or photon drag detectors.
