Terahertz detection using a ridge waveguide

In this study, we demonstrate a terahertz detector for the future development of integrated optical components at these frequencies. The detection of terahertz-waves was achieved using a microstructured lithium niobate crystal in a ridge-waveguide configuration with a heterodyne electro-optics sampling method. The ridge waveguide also enabled broadband terahertz wave detection by reducing the diameter of probe beam.
