摘要：

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 (lambda similar to 100 mum) to similar to33 THz (lambda = 9 mum). Over a band of nearly 20 THz, a relatively flat frequency response is observed. We discuss issues that limit the response bandwidth. (C) 2002 Optical Society of America.
