Paper Title:
Waveguide Structure Design of Adiabatic Optical Directional Couplers Weighted by Sin-Square Function
  Abstract

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 b0 λ (minimum local beat length). Definitely SSF which is proposed can obtain a better result after the structural design.
