Abstract:
1. An optical module, comprising: a plurality of first optical elements each configured to conduct a conversion between an electric signal and an optical signal; a plurality of first electric signal wirings each configured to transmit an electric signal input to one of the plurality of first optical elements or an electric signal output from one of the plurality of first optical elements; a plurality of second optical elements each configured to conduct a conversion between an electric signal and an optical signal; a plurality of second electric signal wirings each configured to transmit an electric signal input to one of the plurality of second optical elements or an electric signal output from one of the plurality of second optical elements; and a plurality of optical waveguides each configured to guide an optical signal emitted from one of the plurality of first optical elements or the plurality of second optical elements, or an optical signal incident on one of the plurality of first optical elements or one of the plurality of second optical elements, wherein the plurality of first optical elements are disposed on a first surface side of the plurality of optical waveguides, the plurality of first electric signal wirings are disposed on the first surface side of the plurality of optical waveguides side by side in parallel with each other in a direction intersecting with a transmission direction of the electric signal transmitted by a first electric signal wiring, the plurality of second optical elements are disposed on a second surface side of the plurality of optical waveguides, the plurality of second electric signal wirings are disposed on the second surface side of the plurality of optical waveguides side by side in parallel with each other in a direction intersecting with a transmission direction of the electric signal transmitted by a second electric signal wirings, and the plurality of optical waveguides are disposed side by side in parallel with each other in a direction intersecting with a waveguide direction of the optical signal guided by an optical waveguide at an interval which is narrower than an interval between adjacent first electric signal wirings and narrower than an interval between adjacent second electric signal wirings.
