A method and integrated optical mode transform device is given whereby an optical waveguide positioned on a support substrate for receiving light from a optical fiber passing through a mode-matcher converting light from one mode to another to minimize optical loss. The integrated mode matcher can be bi-directional, so that when an optical fiber mode entering from the proper side (from the right side), it is transformed into an elliptical mode very similar in dimensions to the integrated optic waveguide. In this operation the mode mismatch with the integrated optical waveguide mode will be small. |
