Classification: CPC G | IPC G

Claim 0:
1. A wavelength division multiplexing device, comprising:
a housing;
a designed optical path at least partially contained within the housing;
an alignment substrate associated with the housing; and
a plurality of collimating lenses each having a waveguide interface surface, an air interface surface, and a collimator optical axis,
wherein the alignment substrate includes:
an upper surface having plurality of integrated optical waveguides each fabricated in the upper surface and including an end face with a waveguide optical axis, and a plurality of aligners each fabricated in the alignment substrate 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.
