DESIGN OF SYMMETRIC AND ASYMMETRIC PASSIVE 3-BRANCH POWER DIVIDERS BY BEAM PROPAGATION METHOD

Highly accurate models of waveguide devices made by diffusion, in general, can be set up for design calculations, employing the effective index and beam propagation methods. The illustrative example on a symmetric three-branch power divider by K+-ion exchange in glass yields excellent agreement between theoretical calculations and measured results on a fabricated device.
