Paper Abstract

Optical switches and variable branching ratio directional couplers by moving prism have been developed. These devices have the ability of no transient switching or free branching ratio. The fluctuation loss phenomenon in switching period and insertion loss increase has not been investigated yet. This phenomenon is reported in this paper. Clockwise prism angular deviations at the assembling process are proved to be the cause of the fluctuation loss and insertion loss increase. Counterclockwise prism angular deviations at the assembling process are useful to eliminate fluctuation loss in the switching period and insertion loss increase in the prism. Details of these arguments are presented in this paper.
