Optimal Design Based on Taguchi Method for Optical Directional Full Couplers of Sin-Square Function

Optimal design based on Taguchi method for optical directional full couplers of sin-square func-tion is investigated. L9 experimental tests based on Taguchi method are performed, and beam propagation method is used to simulate design conditions. The objective of the work includes in the new design of opti-cal directional full couplers can obtain respectively low crosstalk and short couplers. In accordance with this simulation process, the working time of simulation and optimization experimentally can be greatly re-duced. For the sin-square function, we try and find the best sets of coupling waveguide structure parame-ters of adiabatic directional couplers with larger structure tolerance and shorter coupler length, the results can obtain 95% of the trust ranges. The optimal design conditions determined by Taguchi's method for re-ducing the low crosstalk and short couplers were verified experimentally in this work.
