The XQ71B0 micro/nano fiber taper is a high-precision tapered optical fiber designed for advanced optical sensing and photonics applications. Engineered to achieve ultra-small waist diameters with minimal transmission loss, it enables strong evanescent field interaction, making it ideal for high-sensitivity sensing, coupling, and experimental research.

By reducing the fiber diameter to the micro- or nanoscale, the optical mode extends beyond the fiber boundary, creating a pronounced evanescent field. This allows direct interaction between the guided light and the surrounding environment, which is critical for applications such as refractive index sensing, biochemical detection, and environmental monitoring.

The taper fabrication process is optimized to ensure smooth transitions and low insertion loss, preserving beam quality while maintaining mechanical stability. Customization options for taper length, waist diameter, and transition profile enable integration into a wide range of experimental and OEM photonic systems.

These fiber tapers are widely used in research and development environments, as well as in emerging sensing platforms where compactness, sensitivity, and optical precision are essential.
