Abstract
A planar lightwave circuit having a core, a clad stacked on the core covering the core to confine light within the core, and an optical protection layer stacked on the clad covers the clad is disclosed. The clad has a lower refractive index than the core. The optical protection layer is made of a material for absorbing the light leaked from the core to the clad.
Claims15
A planar lightwave circuit, comprising:
- a core serving as a light propagation medium;
- a clad having lower and upper portions, stacked on the core, for covering the core to confine light within the core, the clad having a lower refractive index than the core;
- and
- an optical protection layer, stacked on the clad, for covering the clad, the optical protection layer being made of a material for absorbing the light leaked from the core to the clad.
