SEMICONDUCTOR OPTICAL CONVERTER |
摘要 |
A semiconductor optical converter for use principally in an optical communication system or an optical information processing system. The semiconductor optical converter comprises an n-InP clad layer (12), an optical waveguide layer (13), an SI-InP clad layer (14), and an n-InP clad layer (15) formed sequentially on an SI-InP substrate (11), characterized in that a voltage is applied from an electrode (16) connected with the n-InP clad layer (15) and a ground electrode (17) connected with the n-InP clad layer (12). The semiconductor optical converter is especially applicable as a semiconductor phase modulator or a semiconductor Mach-Zehnder phase modulator operating at low voltages and having a low waveguide loss.
