Microwave Noise Downconversion in Interband Cascade Laser Frequency Combs

A 30.0 MB dataset from figshare, authored by Grzegorz Gomółka and last updated on 2026-04-23. It contains data related to the characterization of chip-scale semiconductor laser frequency combs, specifically exploring the correlation between baseband noise and multi-GHz intermode beat notes in an interband cascade laser emitting near 3.25 μm.

Use Cases

• Analyzing the correlation between MHz-frequency baseband noise and multi-GHz intermode beat notes based on the described measurement.
• Characterizing laser comb coherence without requiring fast photodetectors based on the described downconversion phenomenon.
• Studying the effects of electrical nonlinearities and linewidth enhancement factors on phase-to-amplitude noise conversion in semiconductor lasers.
• Developing simplified assessment methods for frequency comb coherence in wavelength regions where fast photodetectors are unavailable.

Strengths

• Data is shared under a permissive CC-BY-4.0 license.
• Focuses on a specific and novel measurement technique for laser comb characterization.
• File size of 30.0 MB indicates a manageable download and storage footprint.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is stored in MAT format, which may require specific software (e.g., MATLAB) for access and analysis.
