Abstract: Transitions between subbands in semiconductor quantum wells were suggested as a method to generate long wavelength radiation at customizable frequencies. The recently developed THz quantum-cascade lasers (QCL) hold great promise to bridge the so-called "THz gap" between conventional electronic and photonic devices.Using the high-power THz QCL and a 240x320 focal-plane array camera, we are now able to perform real-time THz imaging at video rate, that is, taking movies in "T-rays".
