Lamping process and application of ultra small U-shaped, whispery gallery mode (WGM) based optic fiber sensors

摘要

This study success to smaller and control the diameter of single mode optical fiber whispery gallery mode (WGM) to diameter 0.8 mm nonetching and nontaping treated. The sensitivity of this type ultra-small U-shape WGM strengthens neither etching nor taping fibre. The sensitivity we apply to thermo test depends on wavelength shift from 40 ～ 96 °C (R~2 = 0.99). The specially characteristics of the optical fiber could be tested for temperature, refraction, vibration, concussion, and CO_2 detection.
