Challenges, Risks, and Strategic Opportunities
The carbon nanotube (CNT)-based photonics sector is poised for significant growth in 2025, but it faces a complex landscape of challenges, risks, and strategic opportunities. One of the primary challenges is the scalability of high-quality CNT synthesis. Achieving uniformity in chirality, diameter, and length is critical for consistent optical properties, yet current production methods often yield heterogeneous mixtures, limiting device performance and reproducibility. This issue is compounded by the high cost and technical complexity of purification and sorting processes, which can hinder commercial viability and large-scale adoption Nature Reviews Materials.
Another significant risk is the integration of CNTs with existing photonic platforms. While CNTs offer unique advantages such as tunable bandgaps and strong light-matter interactions, their compatibility with silicon-based photonics and other established materials remains a technical hurdle. Issues such as interface stability, contact resistance, and thermal management must be addressed to ensure reliable device operation, especially in high-speed or high-power applications Optica Publishing Group.
Regulatory and environmental concerns also pose risks. The long-term health and ecological impacts of CNTs are not fully understood, and evolving regulations could affect manufacturing, usage, and disposal.
