Abstract

A method of manufacturing passive integrated optical devices from polymeric materials, the method comprising providing a step structure at each transition between a fiber alignment structure and the preform for the light waveguide structure, wherein both of these structures are produced simultaneously. Passive integrated optical devices having ridges or trenches with rectangular cross sections and manufactured to this method are also described.
