چکیده انگلیسی
In the fabricating process of a 3â¯Ãâ¯3 fused tapered coupler, the three fibers are usually twisted to be close-contact. The effect of twist on 3â¯Ãâ¯3 fused tapered couplers is investigated in this paper. It is found that though a linear 3â¯Ãâ¯3 coupler may realize equal power splitting ratio theoretically by twisting a special angle, it is hard to be fabricated actually because the twist angle and the coupler's length must be determined in advance. While an equilateral 3â¯Ãâ¯3 coupler can not only realize approximate equal power splitting ratio theoretically but can also be fabricated just by controlling the elongation length. The effect of twist on the equilateral 3â¯Ãâ¯3 coupler lies in the relationship between the equal ratio error and the twist angle. The more the twist angle is, the larger the equal ratio error may be. The twist angle usually should be no larger than 90° on one coupling period length in order to keep the equal ratio error small enough. The simulation results agree well with the experimental data.
