Abstract

Second harmonic generation (SHG) by quasi-phase matching (QPM) in LiNbO3 waveguides has recently attracted a great deal of attention. Using periodically domain inverted grating on LiNbO3, normalized conversion efficiency of order of 20 ~ 80%/W.cm2 have been achieved.1-4 However, the phasematching bandwidth length product is rather small for QPM waveguides, thus imposes a very critical limit on the diode pump sources. Temperature tuning of the QPM wavelength in LiNbO3 waveguide have been demonstrated,3 a tuning rate which is comparable to the diode laser temperature tuning can be achieved. However, in order to obtain stable SHG output, a fast responding fine tuning scheme is required for the electronic feedback stabilization system. In this paper, we demonstrate the wavelength tuning and modulation of the quasi-phase matched SHG signal using the electro-optic (EO) effect in LiNbO3 waveguide.
