OPTICAL WAVEGUIDE DEVICE |
摘要 |
An improved optical waveguide device having an optical waveguide for guiding a lightwave comprises, on a surface of a substrate having an electrooptical effect, at least a pair of electrodes composed of a hot electrode and a ground electrode which controls a guided lightwave, a buffer layer formed between the electrodes and the optical waveguide; further comprising an antistatic film which is formed on an upper surface of the buffer layer such that it comes into contact only with the hot electrode.
