Optical control device and method for making the same |
摘要 |
Disclosed is an optical control device which has a LiNbO3 or LiTaO3 crystalline substrate having electrooptic effect; a channel-type optical waveguide which is formed in the crystalline substrate by doping metal; an optically transparent film layer formed on the crystalline substrate; and electrodes formed on the optically transparent film layer; wherein the crystalline substrate has a surface except a region which waveguided-light through the channel-type optical waveguide propagates or an entire surface under which a layer doped by metal is formed.
