Microprobe cantilever design:
The TeraSpike TD-1550-Y-BF is a microprobe emitter based on patent pending design (DE 10 2013 020 216.7) for the bias-free surface-near excitation of Terahertz pulses on planar waveguides, metallic surfaces or meta-materials. The optically generated THz field is polarized in y-direction.
Configuration: THz pulse generation on a thin-film microstrip line using the bias-free TeraSpike emitter microprobe. For on-chip contact-free THz field detection a second TeraSpike probe from the TD-800-X or Z series can be applied.
THz Emission scheme: 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.
|Excitation wavelength||700 .. 1600 nm|
|Average excitation power||0.1 .. 4 mW|
|Emission bandwidth (for 90 fs pulse excitation)||> 2.5 THz|
