Abstract

A number of different methods of generating Terahertz radiation is considered and the efficiencies of these methods are compared theoretically between themselves as well as with Manley-Rowe limits. It is shown that below 1 THz photoconductive antennae and traditional microwave methods hold advantage, while above 10 THz the advantage goes to traditional nonlinear optical methods. In the 1 - 10 THz region there is no clear winner, but the methods using intersubband transitions in quantum wells do possess significant advantage.
