A clear encapsulation is applied to an initial wafer including active optical components and a wafer-size substrate. Thereon, a photostructurable opaque coating is produced which includes apertures.

Cutting through the opaque encapsulation material present in the trenches, singulated optical modules are produced, wherein side walls of the intermediate products are covered by the opaque encapsulation material. The wafer-size substrate can be attached to a rigid carrier wafer during most process steps.
