Open the CIPO recordAbstract From the Canadian patent
An optical interconnect is formed from a series of coaxially aligned lenses. The lenses are spaced apart along a planar substrate (1) and form repeated images of an optical array (9) at the input to the interconnect. Output ports are located at different points along the interconnect. Each of the pair of lenses enclosing one of the repeated images is formed as a single physically integral member (3). This member (3) may take the form of a transparent rod having spherical end surfaces. Each of the spherical end surfaces then provides one of the pair of lenses.

Why it's free to use
- Filed February 14, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 14, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 14, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
