Optical fiber adapted to manufacture gain equalising filters for doped fiber amplifiers |
| 摘要 |
<p>The fibre optic filter has a center (10) and a photosensitive sleeve (20) sensitive to radiation and having a periodic refraction index perturbation. A Bragg network is formed having a slope with respect to the longitudinal axis and having only a small refraction index difference between the center and outer sleeve.</p> |
