Abstract :
A detector of the terahertz (THz) electric field with a quasi phase-matched electro-optic crystal is presented. This detector exhibits enhanced sensitivity in comparison to the standard detector design. The detector performance is demonstrated using broad- and narrow-band coherent THz sources.
