Abstract
A multilayer ceramic substrate 11 is used, and a prism 14 serving as a component of a hybrid optical module and a chip 12 on which an optoelectric converting element is mounted are mounted on different layers of the multilayer ceramic substrate. The thickness of the chip on which the optoelectric converting element is mounted is substantially equal to the depth of the layer of the multilayer ceramic substrate on which the chip is mounted.
Claims1
A hybrid optical module comprising:
- a multilayer ceramic substrate on which an optoelectric converting element is mounted, and
- a prism which controls incidence and emission angles of light is directly mounted on a layer of said multilayer ceramic substrate that is different from the layer on which said optoelectric converting element is mounted,
- wherein said optoelectric converting element is mounted in such a manner that a thickness of said optoelectric converting element is equal to a depth of an arbitrary layer of said multilayer ceramic substrate on which the optoelectric converting element is mounted, and
- said optoelectric converting element is wire-bound to said arbitrary layer.
