We report the generation and coherent detection of freely propagating ultrashort baseband electromagnetic pulses. Using optical rectification in 〈110〉 GaAs for wideband emission and electro-optic sampling in a poled polymer for wideband detection, we demonstrate spectral sensitivity that extends from the far infrared (λ~100 μm) to ~33 THz(λ = 9 μm) . Over a band of nearly 20 THz, a relatively flat frequency response is observed. We discuss issues that limit the response bandwidth.
