Open the CIPO recordAbstract From the Canadian patent
The invention concerns a very high bit-rate soliton regenerator including a non-linear optical loop mirror or NOLM (3) receiving a soliton signal ensuring its modulation by a control. The regenerator also includes a control generating device (5) using pulses from two optical sources (11 12), the frequency of at least one of the two sources being variable and keyed to the modulated soliton signal for example to its power, or keyed to an optical phase-locked loop. The result is a soliton regenerator which uses only low-frequency electronic components and which can regenerate a soliton signal at a very high bit-rate.

Why it's free to use
- Filed January 2, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 2, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 2, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
