摘要

This study discusses optimization of the adiabatic optical directional coupler (AODC) based on sin-square weighting functions (SSF) for waveguide structure. The objective of the work includes the define coupler of theory ranges, low crosstalk and short coupler length, respectively. When the crosstalk is demanded to be smaller than -35 dB, the coupler length for SSF is 2 λb0 (minimum local beat length). Definitely SSF which is proposed can obtain a better result after the structural design.
