| Abstract: | Based on a coupled-mode theory, the power transfer among many parallel single-mode optical fibers formed into "--" has been investigated. The analysis shows that the distance between each of the N fiber centers has an effect on the coupling coefficient and power transfer. The solution of the coupled-equation for three parallel single-mode optical fibers has been given, and is comparatively studied for different initial conditions. Numerical simulations show that power transfer will be periodical when coupling occur among many parallel single-mode optical fibers formed into "--". |
