Summary :

Design theory of coupled-waveguide optical modulator/switch with pn junction is presented for a new structure with two parallel strip-loaded channel waveguides, and numerical analyses on GaAs and GaAs-AlxGa1-xAs devices at 1.06µm are carried out. It is analyzed that P/f (modulating power per bandwidth) is much smaller in this device than in its predecessor with multi-layered structure in planar waveguide configuration, and that promising devices with P/f for 100% modulation as low as 22 µW/MHz can be designed within the limits of present fabrication technology.
