Open the CIPO recordAbstract From the Canadian patent
A novel wavelength routing apparatus that uses a diffraction grating (201) to separate a multi-wavelength optical signal from an input port (210)into multiple spectral channels; a channel-interleaving assembly (230) (e.g. an array of prisms) to interleave the spectral channels into two channel groups; and "augmented relay system" (240) to relay the interleaved channel groups onto two separate arrays (203A, 203B) of channel micromirrors respectively. , The channel micromirrors are individually controllable and pivotable to reflect the spectral channels into multiple output ports (210). The inventive wavelength routing apparatus can route the spectral channels on a channel-bychannel …

Why it's free to use
- Filed August 29, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 29, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 29, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
