Latest Patents
Frederic Pommereau holds a patent titled "Method of forming a layer of silica to be eliminated subsequently." This patent describes a method for mounting an integrated optical component. The starting base structure includes a silica lower confinement layer and the cores of future optical waveguides. This basic structure features an alignment abutment, allowing for precise alignment of the mounted component with the waveguides. A silicon barrier layer is deposited on the abutment, followed by the application of an upper silica layer using flame hydrolysis deposition. This upper layer serves as the confinement layer for the waveguides and also covers the alignment abutment. To expose the abutment, the region is etched by reactive ion etching, with the barrier layer protecting it from damage. The component is then accurately located relative to the abutment.
