Abstract
We present the design of a short broadband fiber directional coupler for terahertz (THz) radiation and demonstrate a coupler with a bandwidth of centered at . The broadband coupling is achieved by mechanically downdoping the cores of a dual-core photonic crystal fiber by microstructuring the cores. This is equivalent to chemical downdoping but is easier to realize experimentally.
