Non linear thin layer optical device |
摘要 |
The invention relates to non-linear optical devices in which significant non-linear interactions are obtained by establishing a "quasi phase matching". The optical device according to the invention comprises on the surface of a substrate a periodic structure formed of zones in which the non-linear coefficient alternately assumes two values of opposite signal. The invention also relates to a process for producing this device. The invention allows generation of harmonics, frequency changing, parametric amplification or parametric oscillation.
