A functional optical device has cores which are trenches, different portions of the cores being formed from different core materials. The optical device can be formed by forming trencheswithin a substrate (normally a substratecovered by a cladding layer), covering at least part of at least one trenchwith a cover, depositing a first cladding material to fill the trencheswhich are not covered, removing the cover, depositing a second cladding layerof a second cladding material to fill the trencheswhich were previously covered, removing core material outside the trenchesand applying a cladding layer to cover the trenches.
