Ti:LiNbO(3) waveguide electro-optic beam combiner.
We demonstrate a low-loss Ti:LiNbO(3) waveguide circuit for lambda = 1.55 microm that under voltage control can be used to combine two mutually coherent input beams of arbitrary relative amplitude and phase into a single-output waveguide while suffering only propagation losses.
