A novel SH generator based on a photonic band gap (PBG) mixed half-quarter-, wave, periodic structure is described. Both energy output and conversion efficiencies are nearly three orders of magnitude greater than for bulk phase-, matched devices of comparable lengths. Similiar results for a GaAs/AlAs semiconductor periodic structure are also found. These results have immediate applications in frequency up- and down-conversion lasers higher and lower , harmonic generation and Raman-type lasers, where either Stokes or anti-Stokes resonances can be enhanced or suppressed near the band edge. In general the , underlying mechanism requires the fields to be strongly confined allowing for , …

Listed from its CIPO record in Patent Yard's archive of Canadian patents past their term. Its claims, description and drawings are in the CIPO record and on Google Patents, and the Claude kit works from them.
Why it's free to use
- Filed April 2, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 2, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 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.
