Technology Overview
The document details a study on boosting THz generation by using a new heterogeneous layered structure to address the substantial Fresnel losses seen in standard THz generation setups. This structure utilizes intermediate layers with refractive indices closely matching those of the organic nonlinear optical crystal DAST, incorporating materials like BK7 glass and high-density polyethylene (HDPE), and recommends MBBA for its low THz absorption.
Key Advantages
- Nearly 50% improvement in THz power output
- Significant reduction in Fresnel reflection losses
- Enhanced transmission coefficients at both input and output phases
- Potential for further improvements with anti-reflective coatings
Problems Addressed
- Substantial Fresnel losses in standard THz generation setups
- Large refractive index mismatches between air and organic nonlinear optical crystals
- Reflection losses that inhibit the efficiency of THz output
