  • Abstract
    A novel guided-wave optical frequency shifter has been fabricated in a Y-cut LiNbO3 substrate. This frequency shifter utilizes acoustooptic (AO) Bragg diffraction in cascade to maintain the propagation direction of doubly diffracted light with tunable frequency shift. A frequency shift with center frequency of 1 GHz and a -3-dB bandwidth of 165 MHz has been obtained with this preliminary device. The resulting integrated-optic frequency shifter module should be applicable to heterodyning integrated- and fiber-optic systems
