TERAHERTZ SYSTEMS
Compact, Portable Terahertz Spectroscopy System
EMCORE’s versatile PB7220-2000-T Spectroscopy Platform is designed for scanning
complex compounds to precise specifications with greater accuracy and control. The
PB7220 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 PB7220 can
sweep from 100 GHz to over 1.8 THz in a single rapid scan with frequency resolution
better than 0.25 GHz.
The PB7220 employs precisely tuned, fiber coupled, butterfly packaged semiconductor
DFB lasers, an advanced photo-mixing source and detector, and sophisticated digital
control hardware and software to provide a fully turnkey 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
o Explosives
o Biologicals
o Chemicals
Unlike time-domain systems requiring expensive mode-locked lasers, the tunable
semiconductor laser diodes in the PB7220 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 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 to provide
maximum measurement flexibility in a wide range of applications.

Terahertz Performance
Typical performance of a PB7220-2000 - THz Spectrometer for a scan of laboratory air at 1 ATM. 1 sec time constant.
Air at 1 ATM with water vapor. No processing was performed because head spacing was adjusted to remove
interference fringes from the regime of interest.

Graphical User Interface
The PB7220 includes highly functional software for Windows 7 PCs. Besides being able to control the frequency of the system with the
Dwell or Scan, it is now also possible to do averaging, background subtraction, normalization and smoothing all from the same interface.
The calibration files are installed into the PB7220, and if a new computer is connected to the PB7220, the calibration files are
automatically downloaded to the computer. This makes it easy to move the PB7220 to different computers.
