INTEGRATED-OPTICS POCKELS CELL - CHOICE OF CRYSTAL CUT AND WAVE-GUIDEORIENTATION

Several benefits are realized when one chooses z-propagating waveguide in a y-cut substrate of lithium niobate for use in an integrated opti cs Pockels cell: (1) waveguide can be biased by controlling its length ; (2) polarization state is nearly uniform over the entire output plan e of the waveguide; (3) temperature change does not significantly affe ct the bias of the waveguide; (4) optical damage is negligible; and (5 ) waveguide fabrication is very simple.
