Abstract :
An enhanced electro-optic detector of the far and mid-infrared radiation is presented. A quasi-phase matching approach is used to address low sensitivity of the detector at multi-terahertz frequencies. Demonstrated concept enables to increase the sensitivity especially for the high frequencies by order of magnitude.
