Y-Branched Multimode/Single-Mode Polymer Optical Waveguides for Low-Loss WDM MUX Device: Fabrication and Characterization

Fabrication of Y-Branched GI Core Polymer Waveguide and its Application to CWDM MUX Device for Multimode Fiber

“…During these interim times in both methods, we expect the core and cladding monomers to diffuse, forming a concentration distribution in the core. The detailed fabrication conditions are described in [10].…”

“…The core pattern design is optimized to minimize the insertion loss, as described in [10] applying the beampropagation method (BPM). In order to fabricate low-loss GIcore Y-branched waveguides, the possible structures and the material combinations of core and cladding are limited.…”

“…In order to address the aforementioned issues, we have demonstrated that GI core waveguides exhibit low propagation and coupling losses due to the strong light confinement in the GI core [5,6]. Accordingly, for low loss and high-bandwidth CWDM-MMF links, we have proposed Y-branched GI core polymer optical waveguide couplers [7][8][9][10].…”
