CPS-based on-chip THz TDS platform
Key facts:
- TeraLineX_ultra: A versatile on-chip THz time-domain spectroscopy (TDS) platform based on a low-loss Co-planar stripline (CPS) design.
- Enables THz Spectroscopy: Operates at micron-scale, allowing analysis of devices and samples smaller than the THz diffraction limit.
- Enhanced Interaction: Facilitates interaction with thin-film samples due to planar THz mode propagation.
- Flexible Operation: Can be used in small cryo-chambers at low temperatures and in magnetic fields.
- Cost-Efficient: Supports interchangeable daughter-boards as sample carriers.
- Customizable Configuration: The TLX_ultra can be individually configured for various key parameters (refer to the table below). Additional configurations available upon request.
