Integrated optical router and wavelength convertor matrix

摘要

Embodiments of the present invention provide an integrated wavelength converter and optical router which is based on an optical device which includes upper and lower waveguide structures. The upper wave guide structure includes first and second portions, and includes a reflecting surface for reflecting optical signals between the first and second portions. Each of the portions is able to be optically coupled with a respective part of the lower wave-guide structure, such that optical signals can be coupled between respective parts of the lower waveguide structure.
