Abstract
Abstract Polymer materials have always been considered as promising materials to be hybridized with silica fibers and form prominent optical devices. Therefore, polymeric integrated photonic devices are among the hotspots of optical network research. To rout, distribute and combine light signals throughout multichannel optical system, optical couplers, and optical splitters can play a significant role. Here we fabricate and characterize freestanding X- and Y- shaped polymer coupler and splitter with optical fibers by photopolymerization method. Polymer couplers showed insertion loss in the range between 1.6 dB and 2.6 dB with a small combination of light coupling. Optical splitters were made from polymer tips integrated with fibers and then they were Butt coupled. The optimum optical transmission was achieved with short and thicker input channel and thinner and longer tips at output channels such that a minimum excess loss of 2.9 dB was measured at 532 nm.
