Abstract
The invention relates to improved terahertz radiation sources and associated methods. A terahertz radiation source is described, comprising: an emitter () comprising a semiconductor material (); a pair of electrodes () adjacent a face of said semiconductor, said pair of electrodes defining a gap between said electrodes; a pulsed light source input for illuminating said semiconductor to excite photo-carriers in said semiconductor to generate terahertz radiation; and a radiation collector () to collect said terahertz radiation; and wherein said radiation collector is disposed on the same side of said semiconductor as said electrodes. A related method of providing terahertz radiation is also described.
