A SEM image from a Complementary Split Ring Resonator processed by Electron Beam Lithography. The resonators have different gap sizes of 2 um and 250nm.
3D illustration of a double metal waveguide THz quantum cascade laser. The active region is sandwiched between two metallic plates, with wires bonded on the top metal.
