Popis:	Theoretical coupling of a guided Gaussian beam in a planar dielectric waveguide to a rectangular waveguide using a lenslike coupling region is investigated. The coupling region is formed by varying the thickness of the planar waveguide. When the center height of a sample structure is of the order of 1.58 wavelengths, a 100-lambda wide beam can be coupled to a linear waveguide 5 lambda wide in a distance of 957.35 lambda. The theoretical coupling efficiency approaches 100%.
