Optical module and a method for manufacturing an optical module
The invention is a method for manufacturing an optical module where on forms a groove in a substrate for positioning a component such as an optical component. The optical component is provided to be bonded into the groove by a aluminum oxide bonding process. To prepare the bonding an aluminum layer is deposited on the optical component followed by a protection layer.
