Patent ID: 7457490

Claim:
A method of manufacturing an integrated optical system comprising the steps of: providing a wafer with active optical components, each active optical component having an optically active surface; providing optical structures allocated to the active optical components operable to influence electromagnetic radiation emitted by the optically active surface and/or electromagnetic radiation impinging on said optically active surface, wherein the optical structures are provided by the following steps: by adding a protection layer to the wafer, the protection layer partially covering the wafer's surface, by disposing transparent material in a liquid or plastically deformable state, on at least some of the active optical components, by replicating the optical structures by a replication tool, in an aligned manner, in a surface of said transparent material, wherein in the replication process the replication tool abuts the protection layer, or a protrusion thereof, and by removing the protection layer; the method of manufacturing the integrated optical system further comprising the step of separating the wafer with the optical structures into parts containing at least one active optical component and at least one optical structure.
