The PB7100 Series is a frequency-domain system for characterization of samples in the 100 GHz to 2.0THz frequency range. The PB7100 system produces a swept CW source signal that is detected by a swept receiver, in similar fashion to a microwave network analyzer.
This approach overcomes the limitations of previous time-domain FFT-based THz spectroscopy techniques and provides unmatched frequency accuracy, resolution and detection sensitivity in an easy-to-use automated laboratory instrument.The system relies on a proprietary EMCORE advanced heterodyne semiconductor laser hybrid photonic "engine" to generate pure CW THz signals over a broad frequency range, working in concert with a patent-pending low-noise THz detection technique to achieve unprecedented performance in a compact form factor without cryogenic cooling.
In addition, we have an active development program in THz technology and also develops customized solutions based on its extensive portfolio of intellectual property
