Research ArticleOpen accessIn the abstractA Novel Thermooptic Polymer Switch Based on Directional Coupler StructureAbu Sahmah Mohd Supa’at, Mohd. Haniff Ibrahim, Abu Bakar Mohammad et al.A novel thermooptic (TO) polymer switch based on directional coupler structure is proposed for the first time. The key element of the proposed switch is a buried square core polymer waveguides which has been designed for optimum mode matching and coupling with the single mode optical fiber configuration and have large effective index difference by the thermooptic effects. At a … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 6,374 accessesView PDF Cite
