ABSTRACT:
An optical module of the present invention includes a first substrate1, a second substrate2, a PD3, a LD4, and an optical fiber5. The first substrate1has a first optical waveguide core1cformed therein. The second substrate2has a second optical waveguide core2cformed therein. The first optical waveguide core1cand the second optical waveguide core2cform an optical connecting portion where the first substrate1and the second substrate2are bonded to each other. The LD4is capable of transmitting an optical signal via the second optical waveguide core2cand the optical fiber5. The PD3is capable of receiving an optical signal which enters the second optical waveguide core2cfrom the optical fiber5, and propagates through the first optical waveguide core1cvia the optical connecting portion formed between the first optical waveguide core1cand the second optical waveguide core2c.
