Terahertz Quantum Cascade Laser Modulation Data with Acoustic Phonon Pulses

University of Leeds research data from an experiment demonstrating high-speed modulation of a terahertz quantum cascade laser using coherent acoustic phonon pulses. The dataset includes power-current, power-voltage characteristics, voltage and Schottky signal measurements, resonant tunneling data, and simulation files for predicted power modulation. Aniela Dunn authored the associated paper, which reports a maximum modulation depth of 6% and a measured rise-time of approximately 800 ps.

Use Cases

• Modeling laser modulation dynamics based on power-current and power-voltage characteristics.
• Analyzing the relationship between bias conditions and device signals based on voltage and Schottky detector data.
• Validating perturbation theory models for laser gain modulation using the provided simulation data.
• Investigating resonant tunneling effects in quantum cascade structures based on the included resonant tunneling data.

Strengths

• Includes multiple complementary data types: experimental L-I/L-V curves, voltage signals, resonant tunneling data, and simulation files.
• Data is directly associated with a published scientific paper, providing methodological context.
• Specific experimental results are reported, such as a 6% modulation depth and an ~800 ps rise-time.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and overall dataset scale are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
