| 摘要 |
A method of filtering optical noise generated by an optical component (2) in a planar photonic device (1), includes the step consisting in placing refractive index change regions symmetrically on either side of the path of the light downstream from the optical component (2), said regions being adapted to prevent forward propagation of the light outside said path. The refractive index change regions can be constituted by trenches (10) or by regions (20) possessing sawtooth-shaped elements (25). The invention also provides a planar photonic device in which said method is implemented. |
