Abstract
An embodiment of the present invention relates to a method of fabricating an optical device, the method comprising the steps of:
- depositing a photoresist layer on a carrier, said photoresist layer containing at least one optical component,determining the position of the at least one optical component inside the photoresist layer before exposing the photoresist layer to a first radiation, said first radiation being capable of transforming the photoresist layer from an unmodified state to a modified state,elaborating a device pattern based on the position of the at least one optical component, andfabricating the elaborated device pattern by locally exposing the photoresist layer to the first radiation and locally transforming the photoresist layer from the unmodified state to the modified state.
