Abstract

We developed an apodized multiple quasi-phase-matched (QPM) LiNbO 3 device to reduce the cross talk that occurs during waveband conversion. Since we found that the cross talk arises from ripples between multiple QPM peaks in the phase-matching curve, we reduced the amplitude of the ripples by employing the apodized structure. Using this device, we succeeded in demonstrating waveband conversion with low cross talk.
