Passive-type ultra-fast detector for sub-THz radiation range.
This product is an ultimately user-friendly plug & play device.
All you need to put it to use is an oscilloscope (or any other
type of voltage detector), which is to be pluged to a coaxial
SMA type output connector and then exposed to a THz or
sub-THZ radiation under investigation.
TeraSense® detector response time was measured using
mixing method at local oscillator frequency of 97 GHz.
Photoresponse of the detector measured as a function
of differential frequency Δf is shown in Figure to the left.
Photoresponse cut-off differential frequency f0 = 3.75 GHz,
which corresponds to response time of 300 ps.
TeraSense® detectors are sensitive in a wide frequency
range. However, due to radiation interference within the
bulk of detector’s crystal, its responsivity consists of multiple
peak structures (see example in Figure to the right). Most
importantly, our specialists — having full control of the
technology- can tune up positions of the peaks in
responsivity curve at manufacturing stage. This way, being
offered such attractive and free customization opportunity,
our clients can choose and order specific frequencies or
frequency ranges they need, when making their purchase request.
Our ultrafast high-sensitive sub-THz detectors are meant for exploring fast-changing and transient
sub-THz signals and impulses. Terasense detectors are actually expediting the advetn of
ultra-high-speed wireless telecommunication networks that is about to happen in the nearest
future. Terasense ultrafast detectors are also an ultimate tool for characterization, calibration
and tuning of impulse sub-THz sources.
