Temperature-independent optical multiplexer and/or demultiplexer |
摘要 |
The present invention concerns a device forming an optical multiplexer and/or demultiplexer of the type including two plane optical surfaces separated by an array of waveguides having controlled differences in length, wherein each waveguide comprises at least two spans placed in series and having respective lengths and refractive indices that are suitable for controlling the influence of temperature variations on the device.
