Abstract

In this paper we discuss three different techniques to generate THz radiation at room temperature with semiconductor lasers. The state of the art is to generate the THz radiation by photomixing of two optical modes in a photoconducting antenna. We show that the complexity of this setup can be reduced by using a laser system emitting two colors simultaneously. Optical power is in excess availiable by using an optical amplifier. In a second approach we demonstrate, that the complexity and cost of the setup can be significantly reduced, by generating the THz radiation directly in the two color laser. This is realized by making use of nonlinear processes in the carrier system. While all these methods generate cw radiation, we finally suggest a third approach to generate pulsed THz radiaton with semiconductor lasers. This THz source can be used in THz time domain systems.
