Design of a four-branch optical power splitter using III-nitride semiconductors

Abstract

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.
