摘要: The generation of broadband terahertz pulses on the facet waveguides is presented as an alternative to widely used coupling techniques. Dielectric loaded subwavelength waveguide structures with lateral confinement are investigated respect propagating modes and losses. results show emitter be a promising tool for spectroscopy in near field probing microstructured devices such quantum cascade lasers.
