Quasi-phase-matching waveguides

The analysis of organic polymer waveguides with quasi-phase matched structures has also been theoretically addressed, taken into account pump depletion and attenuation [11].

Using quasi-phase matching in a periodically poled LiNbOs waveguide structure, a DFG-device with high output power tunable around 1.5 pm was reported in [598], where a Tiisapphire laser at A = 748 nm and a tunable erbium fiber laser were mixed in the nonlinear crystal.
