OPTICAL MODULE

摘要

The objective of the present invention is to provide an optical module enabling a compact profile to be achieved in consideration of making connections to an optical fiber, even when a multichip integrated device is mounted on the optical module. An optical module (110) has an integrated multichip integrated device accommodated in a package (111), the integrated multichip integrated device having a planar lightwave circuit (PLC) (113a, b) connected at both ends of an optical function member (112). A reverse waveguide (131a, b) is formed in each of the PLCs, a waveguide formed on the optical function member and optical fibers (114a, b) being connected via the reverse waveguides (131a, b). Also, connection parts (120a, b) for connecting the optical fiber and the optical function member are connected on the same face on each PLC, each of the optical fibers being led out from the face opposing the package.
