[ACM Press the 2017 International Conference - Osaka, Japan (2017.10.22-2017.10.24)] Proceedings of the 2017 International Conference on Telecommunications and Communication Engineering - ICTCE '17 - Design of a four-branch optical power splitter using III-nitride semiconductors
摘要： This paper reports the design of a four-branch optical power splitter using MMI structure and taper output branches in III-nitride semiconductors. The numerical experimental is conducted using the 3D FD-BPM method. The results show that the optical power splitter has an excess loss of 0.27 dB and imbalance of 0.12 dB. It is also shown that the proposed design can be realized for C band range. This result opens the opportunity for the future device using this technology.

Multiport optical power splitter design based on coupled-mode theory
摘要： We proposed a multiport T-shaped 1 x 8 balanced optical power splitter design based on asymmetric vertical silicon slot waveguides working on the principle of coupled-mode theory (CMT). The scheme of the power splitter is unique which offers strong field confinement of TE-polarized light and delivers the light to four ports each on two opposite side of the chip. By shifting the slot towards the outer sideline of the bend, the bending losses are reduced to 80% as compared to standard symmetric slot waveguide.

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.
