A microprobe that generates THz pulses right at the surface — on planar waveguides, metallic structures or metamaterials. No bias voltage, no contact: optical excitation of the InGaAs cantilever is all it takes.
THz pulse generation is based on optical excitation of the InGaAs micro-cantilever surface. Placing the excited tip close to a conductive structure or surface allows efficient capacitive coupling and pulse transmission. The optically generated field is polarized in y-direction.
Configuration example (top of the page): THz pulse generation on a thin-film microstrip line. For contact-free on-chip detection a second TeraSpike probe from the X or Z series is applied.
