Abstract:
An analysis of the butt-joining coupling between two inhomogeneous planar optical waveguides with hyperbolic secant refractive-index profiles is made from the point of view of geometrical optics. Furthermore, the design of a new device to contract or expand a collimated beam is presented, and a relationship between sizes of the input and output beams is obtained.
