Abstract :
A novel technique for the lithographic definition and the fabrication of domain reversed regions in LiNbO3 is reported, with application to periodic structures for second harmonic generation (SHG). For the first time, to the authors´ knowledge, domain reversal has been achieved on the negative c-face of the crystal. Such a structure should be useful for quasi-phase-matched SHG of infrared laser radiation.
