New Terahertz Spectroscopy System Balances Resolution Trade-offs
SPRATS platform offers combined spectral and spatial precision for characterizing high-Q THz devices
-
1
The SPRATS system combines asynchronous optical sampling with a micrometer-scale probe for high-resolution THz spectroscopy.
-
2
SPRATS achieves 100 MHz spectral resolution and 20 µm spatial resolution, addressing limitations of conventional THz setups.
-
3
The system successfully studied a silicon dual-period grating, confirming predictions of field localization and phase distributions.
-
4
SPRATS improves far-field resonance measurements by isolating signals from central device regions, reducing edge effects.
-
5
This technology could enhance narrow-line width filters, THz sensors, and advance research in light-matter interactions.
