Abstract
The optical waveguide system comprises a mode discriminating coupler and reflective mode coupling means. These components can be combined in a variety of ways to perform a variety of functions. Among them are drop multiplex devices, add multiplex devices, add/drop multiplex devices, and power combiners. The device combinations can have low loss as well as high reliability, the latter due to the robust structure of the devices.
