PB7200 Portable Frequency Domain

Terahertz Spectrometer

DATASHEET | AUGUST 2013

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.

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.

Applications

Threat Signature Characterization

o Explosives

o Biologicals

o Chemicals

Microwave and THz Spectroscopy

Materials Characterization

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.
