Embodiment Construction
[0039] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.
[0040] The invention provides a silicon-based high-speed dual-carrier dual-polarization modulator integrated chip, which includes 2 single-mode vertical coupling gratings, 2 modulation modules, 1 2×1 multi-mode interference coupler, and 1 dual-mode vertical coupling grating . Silicon-based transverse electric mode (TE0) waveguide connection is used between the two single-mode vertical coupling gratings and the two modulation modules, wherein the transverse electric mode is transmitted; between the modulation module and the 2×1 multimode interference coupler, and The 2×1 multimode interference coupler and the dual-mode vertical coupling grating are connected through a multimode waveguide, in which the transverse electric m...
