Microsplitter module for optical connectivity |
| 摘要 |
A compact optical splitter module is disclosed. One type of compact optical splitter module is a planar attenuated splitter module that includes a branching waveguide network having j>=1 50:50 splitters that form up to n<=2j output waveguides having associated n output ports, wherein only m<n output ports are suitable for transmitting light to the at least one external output device. This provides a 1xm splitter module wherein each output port has the attenuation of a 1xn splitter module, thereby obviating the need for external attenuation. Another type of compact optical splitter module is a direct-connect splitter module that eliminates the need for an optical fiber array when coupling to external optical fibers. Another type of compact optical splitter module is a microsplitter module that serves as device and module at the same time and that eliminates the differentiation between device and module. The integration of device and module also makes manufacturing the microsplitter module cost-effect. Embodiments of microsplitter modules that account for differences in the coefficient of thermal expansion of the materials making up the microsplitter are also disclosed.
