Definitions
- Figure 1 is a cross-sectional view of a waveguide of a magneto-optical microring resonator
- the magneto-optical microring resonator adopts a SiO 2 /Si/Ce:YIG/SGGG structure. Specifically, the structure of the magneto-optical microring resonator is grown on the SGGG. The magneto-optical material, the Ce:YIG layer is used as the cladding of the chip waveguide structure, and the silicon waveguide core layer is formed by the silicon spacer SOI structure, and is covered with the metal microstrip loop directly above the magneto-optical micro-ring waveguide, and passes through the both ends of the pad. Connect an external circuit.
- the external optical signal is input to the input interface through the coupling grating, and then passed through a 2 ⁇ 2 3dB optical coupler, and then divided into two groups of clockwise and counterclockwise propagation.
- the optical signal is coupled into the series double-ring magneto-optical microring resonator through a straight waveguide connected in series by the second port, and propagates in opposite directions in the magneto-optical microring resonator, and the external driving circuit applies the metal microstrip loop through the metal pad.
