Open the CIPO recordAbstract From the Canadian patent
An optical device for use in data communication technique is presented. The device comprises a combination of two spaced-apart waveguides and at least two spaced-apart resonator-cavity loops. The resonator-cavity loops are accommodated between the two waveguides and connected to each other through sections of the waveguides in such a manner that the resonator-cavity loops and the waveguide sections create a closed loop compound resonator for storing optical energy of a predetermined frequency range. A control means is used for controlling physical characteristics of the compound resonator to adjust its optical storage characteristics.

Why it's free to use
- Filed October 15, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 15, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 15, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
