Abstract:
1. An optical module manufacturing method comprising: forming a first waveguide layer and a second waveguide layer on a first substrate and a second substrate respectively, or forming a first waveguide layer and a second waveguide layer on a first surface of a first substrate and a second surface of the first substrate respectively, wherein the first waveguide layer and the second waveguide layer each comprises at least one optical channel, wherein the first waveguide layer is located above the second waveguide layer, and wherein the first waveguide layer is parallel to the second waveguide layer; disposing the first substrate on the second substrate such that the first substrate is parallel to the second substrate, and the first waveguide layer is parallel to the second substrate; disposing a filter at an end of the first waveguide layer and the second waveguide layer such that the filter is aligned with the second waveguide layer; and disposing a prism on the filter, so that a first reflective surface of the prism is aligned with the first waveguide layer, and a second reflective surface is aligned with the second waveguide layer, wherein a positional relationship among the filter, the prism, the first waveguide layer and the second waveguide layer enables an optical signal input to the optical channel in the second waveguide layer to enter the filter after being transmitted by the prism, and wherein the positional relationship among the filter, the prism, the first waveguide layer and the second waveguide layer enables an optical signal input to the optical channel in the first waveguide layer to enter the optical channel in the second waveguide layer after being reflected by the prism and to be output through the optical channel in the second waveguide layer.
