Abstract: Optical coatings and methods of fabricating the same. According to a preferred embodiment, the optical coatings comprise polymeric films formed from the disassociation of chemical products from a gaseous hydrocarbon in plasma. The disassociation process is performed in low-pressure environment and without radio frequency substrate bias. The resultant optical coatings have superior stability, durability and flexibility and may be utilized on highly flexible substrates. The coatings of the present invention can additionally be utilized for multi-layer optical designs and further, may be doped with a polar material to thus cause the coating to possess a desired index of refraction.
