EMCORE Corporation, a leading provider of compound semiconductor-based components and subsystems for the fiber optic and space solar power markets, announced today its latest breakthrough in terahertz technology with the release of the new PB7220-2000-T/R Two-Channel Portable Frequency Domain Terahertz (THz) Spectrometer.
The PB7220-2000-T/R is capable of simultaneous phase coherent measurements of both the transmission and the reflection properties of a sample. The second channel allows a single system to collect sample information at various angles of reflection or scattering from the sample while continuously monitoring the transmission.
The PB7220-2000-T/R expands EMCORE's terahertz spectrometer line which also includes the PB7220-2000-T single channel system. EMCORE's PB7220 series THz spectrometers are designed for THz researchers and application developers who need to study the properties of materials at THz frequencies with high resolution, but don't have the resources or personnel skilled in the complexities of optical measurements. They are truly economical and portable THz systems that can sweep from 100 GHz to over 1.8 THz in a single rapid scan with high-frequency resolution. The PB7220 series employs precisely tuned, fiber-coupled, semiconductor distributed feedback lasers along with a highly advanced photo-mixing source that puts all the THz power at the frequency of interest, yielding excellent signal-to-noise ratios of up to 70 dB Hz across the scan range. In addition, the PB7220 series features sophisticated digital control hardware and software to provide a fully turnkey, portable THz spectrometer system.
"The PB7220 two-channel system is the most significant advancement in our THz technology since the introduction of PB7100 THz spectrometer in 2006," said Dr. Joseph Demers, Director of Advanced Photonics for EMCORE. "The industry has been seeking an economical two-channel system that can allow the simultaneous measurement of both the transmission and reflection properties of a sample. This added versatility in our THz platform makes it an even more valuable and flexible tool for a wider range of research, defense and homeland security related applications," added Dr. Demers.
All PB7220 series models feature fiber-optically-coupled source and detector heads that are mounted on a rail system. The PB7220-2000-T single-channel system utilizes a single rail while the PB7220-2000-R/T two-channel system employs an adaptable optical bench. For both systems the source and detector heads may be detached from the processor unit and used with extended fiber optic cables to provide maximum measurement flexibility in a wide range of applications.
