Embodiment Construction
[0022] like image 3 and Figure 4 As shown, the silicon-based thermo-optic modulator based on the microring resonator of the present invention includes:
[0023] (1) A silicon substrate, the cost of silicon material is low, the process is mature, and it is suitable as the substrate of polymer optoelectronic devices, and silicon is the most widely used material in integrated circuits, and the use of silicon substrates is conducive to the realization of optoelectronic integration.
[0024] (2) A silicon dioxide lower cladding layer is set on the silicon substrate. Due to the large difference in refractive index between silicon and silicon dioxide, silicon waveguides have a strong confinement effect on the optical field.
[0025] (3) Two straight waveguides, arranged on the lower cladding layer of silica, are respectively the main channel waveguide and the lower channel waveguide. The materials are all silicon, which is equivalent to the fiber core. The refractive index of sil...
