Claim 8:
9. A method of making a wavelength division multiplexing device including a plurality of collimating lenses each having a waveguide interface surface, an air interface surface, and a collimator optical axis aligned with a designed optical path, the method comprising:
providing an alignment substrate including an upper surface;
fabricating a plurality of integrated optical waveguides in the upper surface of the alignment substrate each including an end face with a waveguide optical axis;
fabricating a plurality of aligners in the upper surface of the alignment substrate, each of the plurality of aligners associated with the end face of a respective integrated optical waveguide of the plurality of integrated optical waveguides, and configured to receive a respective collimating lens of the plurality of collimating lenses such that when the respective collimating lens is received in the aligner, the aligner aligns the collimator optical axis with the designed optical path at the air interface surface and with the waveguide optical axis of the end face of the respective integrated optical waveguide at the waveguide interface surface; and
placing each of the plurality of collimating lenses in a respective aligner of the plurality of aligners.
