| Abstract: | We have developed a new method to fabricate periodic waveguide structures used for quasi-phase-matched second-harmonic generation, where nonlinear optical organic crystals and fluorinated copolyimides are alternately arranged. Quasi-phase-matched second-harmonic generation from an organic waveguide device has been demonstrated. |
| Keywords: | optical waveguide second-harmonic generation quasi-phase matching organic crystal fluorinated polyimide inorganic photoresist reactive-ion-beam etching |
