The TeraScan ultra is designed to meet the most demanding requirements in THz communications research, channel sounding, wafer inspection, and high-resolution spectroscopy. With a bandwidth of up to 5 THz and ultra-low phase noise, it sets a new benchmark in the generation and control of tunable terahertz radiation.
At the heart of the system are two diode lasers – one tunable, one fixed – both locked to a single optical frequency comb. A photomixer emitter converts the optical beat signal into a tunable, monochromatic THz wave. TOPTICA’s proprietary “endless frequency shifter” ensures seamless frequency tuning while maintaining absolute control over phase and frequency – a crucial requirement for applications like photonic vector network analysis.
The system uses state-of-the-art InGaAs photomixers: a photodiode emitter and a Rh:InGaAs photomixer receiver, both packaged into compact, fiber-coupled modules. Operation modes include fixed frequency, sweep, and triggered step scan – fully software-controlled.
TOPTICA’s TeraScan ultra is ideal for researchers who demand ultimate frequency stability, scanning flexibility, and sub-Hz phase coherence across the full terahertz spectrum.
