Integrated mode transformer for coupling optical wave-guides sets up a wave-guide core for a strip transmission line on a carrier layer while covering the core with a cover layer of same material

摘要

A defined area (B) has a wave-guide core (WKK) made up of single island-shaped strips (TWK) with the same layer stack as the core of a strip transmission line (STL), the core layer stack of which is thinned in the defined area and partly replaced by the lower breaking material of the cover layer.
