Abstract:
A wavelength division multiplexing and optical modulation apparatus includes at least two modulation region-added grating-assisted cross-state directional coupler units and a modulation region-added cross-state directional coupler. The modulation region-added grating-assisted cross-state directional coupler units and the modulation region-added cross-state directional coupler unit are connected to one another in serial. Each of the modulation region-added grating-assisted cross-state directional coupler units each includes a modulation region-added cross-state directional coupler, a grating and a modulation region. The modulation region-added cross-state directional coupler unit includes an output waveguide, an input waveguide and a modulation region.
