Definitions
- a common method is to use silicon slot waveguide (Slot Waveguide) filled with organic electro-optic materials to realize high-speed electro-optic modulators.
- This electro-optic modulator has the advantages of highly concentrated electric field and extremely high electro-optic modulation efficiency, it still has the following problems: 1. The manufacture of the slit waveguide requires a high process; 2. The optical loss is relatively high.
- both the first electrode and the second electrode include:
- the working mode of the waveguide 10 is the TE mode.
- the height of the waveguide 10 can be set according to actual needs, and there is no limitation here.
- the width of the waveguide 10 can be 300nm ⁇ 1000nm.
- the waveguide 10 The width can be 300nm, 400nm, 500nm, 600nm, 700nm, 800nm, 900nm or 1000nm and so on.
- step S20 as shown in FIGS. 3 to 4 , forming the waveguide 10 and the bottom electrode 161 on the substrate 12 may include the following steps:
- the organic electro-optic material layer 11 can be formed by using but not limited to physical vapor deposition process, chemical vapor deposition process or atomic layer deposition process; at this time, the organic electro-optic material layer 11 fills the opening 141 and extends to fill the The gap between the bottom electrode layer 161 and the waveguide 10 ; the structure obtained in step S50 is shown in FIG. 7 .
