| Abstract: | The LiNbOs optical waveguide switch array is an important component in broadband optical communication networks. We have designed and fabricated a 4x4 optical waveguide switch array-5 interconnected directional couplers with alternating A electrooptical modulation. The parameters of the device are: a - lOdb fiber-device-fiber-insertion loss, a - 20 db crosstalk, a 15V-drive voltage, a <1.4 ns response time and a l.3um operating wavelength. |
