Large core optical elastomer splitter fabricated by using 3D printing pattern

The design, fabrication and properties of the large core 1 × 2Y optical planar splitter using optical elastomers for its cladding and core is demonstrated. The splitters were designed by using the beam propagation method, optimized for the operation wavelength of 650 nm. The splitters were fabricated using an epoxy polymer pattern, fabricated by Stereolithography 3D printing technology. The dimensions of the splitters were optimized for assembling an optical fiber with a core diameter of 500 µm. The splitter shows optical losses around 1.48 dB at 650 nm, 1.18 dB at 850 nm, 1.82 dB at 1300 nm and 2.12 dB at 1550 nm.
