Abstract
Organic and polymer materials have been widely used for optical waveguides in high-speed optical communication systems for almost the last two decades because of their easy fabrication at lower cost and high integration for more multiple channels. 1 In addition, optical losses of films fabricated from organic materials are low enough to transmit optical signals error-free and the thermooptic coefficient of the films is ten times higher than that of silica. Since organic materials are optically, chemically, and thermally as stable as inorganic materials and semiconductors when they are used for passively operated optical devices, they are used commercially for passive optical devices such as power splitters, variable optical attenuators, and AWG (arrayed waveguide grating) multiplexers. Optical transmission systems will replace electrical transmission systems for information transmission over short distances (within several centimeters) among drive, memory, display, etc., parts in about five years because mass information transmission with a high speed is needed in information and communication devices such as mobile phones, computers, and digital cameras. Flexibility of the waveguide films fabricated from optical materials has been added to the above-mentioned features of organic materials for optical waveguides. Flexibility is a crucial property for optical waveguide materials for optical signal transmission within mobile devices since optical signals have to be transferred back and forth inside their extremely narrow spaces. Many researchers have investigated various optoelectronic integrated circuits including flexible optical waveguides.2,3 Organic materials suitable for flexible optical waveguides have recently been developed because polymer films have flexibility as an inherent property. However, in this case, an additional substrate film such as polyethylene terephthalate or polyimide was used to obtain the flexible optical waveguides.
