TERAHERTZ SYSTEMS
Compact, Portable Terahertz Spectroscopy System
EMCORE’s versatile PB7200 Spectroscopy Platform is designed for scanning complex
compounds to precise specifications with greater accuracy and control. The PB7200 is
ideal for THz researchers and application developers who need to study the properties
of materials at THz frequencies with high-resolution, but who don’t want to design and
build their own high-resolution THz spectroscopy system. The PB7200 can sweep up
to 2.0 THz in a single rapid scan with frequency resolution better than 0.25 GHz.
The PB7200 employs precisely tuned, fiber-coupled butterfly packaged semiconductor
DFB lasers, advanced photo-mixing source and detector, and sophisticated digital
control hardware and software to provide a fully turnkey laboratory THz spectrometer.
The room temperature solid-state homodyne detection technique eliminates the need
for cryogenics. The highly efficient CW nature of the photo-mixing source puts all the
THz power at the frequency of interest, yielding excellent signal-to-noise ratios across
the scan range of up to 70 dB Hz.
Applications
Threat Signature Characterization

Microwave and THz Spectroscopy
Materials Characterization
Unlike time-domain systems requiring expensive mode-locked lasers, the tunable
semiconductor laser diodes in the PB7200 can support linear scans or can ‘frequency
hop’ between frequencies of interest to scan specific regions of the spectrum with
varying degrees of resolution. The latest ‘snap-in-place’ fiber-optically coupled source
and detector heads are mounted on a rail system and configured for transmission
measurements. They may also be detached from the processor unit and used with
extended fiber optic cables for maximum measurement flexibility in a wide range of
applications, in either transmission or reflection modes. The new terahertz heads
make the PB7200 not only lighter and more compact, but easier to assemble and tear
down.
The PB7200’s latest software package includes smoothing functions and background
subtraction features. The software automatically downloads the calibration files from the
PB7200 which makes setting up multiple computers easy.
