ABSTRACT:
This invention provides superior electrooptic devices containing an organic polymeric waveguiding medium, and a process of fabricating such devices. The fabrication process utilizes a substantially stress-free organic polymeric substrate on top of which the necessary organic layers are successively deposited. The substrate is so selected that its thermal expansion coefficient is substantially close to that of the cladding layers and of the waveguiding layer.
