[IEEE 2019 International Conference on Optical MEMS and Nanophotonics (OMN) - Daejeon, Korea (South) (2019.7.28-2019.8.1)] 2019 International Conference on Optical MEMS and Nanophotonics (OMN) - Low-Loss and Broadband Silicon Photonic Y- Junction Using Tapered Rib Waveguides

摘要： We report on low loss and broad bandwidth X-junctions based on adiabatically tapered rib waveguide silicon photonic devices. The fabricated devices exhibit a compact footprint of 20 μm (taper length), a broad bandwidth over 24 nm, and a low excess loss of 0.28 dB. The demonstrated device has a compact footprint of 20 μm (taper length), a broad bandwidth over 24 nm, and a low excess loss of 0.28 dB.
