Open the CIPO recordAbstract From the Canadian patent
An array of fiber optic RF filters each responsive to a predetermined wavelength forms a channelizer for a wide bandwidth receiver used in a dense signal environment having complex modulations. Each fiber optic RF filter comprises a resonant cavity formed from a section of multimode optic fiber with a dielectric mirror deposited at each end and wherein the cavity length corresponds to one half the respective modulation signal wavelength of optical energy fed into the filter optic cavity from a laser diode which is modulated by the received RF energy.

Why it's free to use
- Filed January 17, 1992 and granted September 7, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 17, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 17, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
