Abstract
- We proposed a 1×N-channel cross-grid microring resonator array (MRRA) model according to the coupled mode theory (CMT), electro-optic (EO) modulation theory, and microring resonance theory. This model integrates wavelength division multiplexing and switching functions. When this model is subjected to an operating voltage, the horizontal channel outputs a new resonance wave. As an example, the 1×8-channel cross-grid MRRA with 1550-nm central wavelength and 0.8-nm wavelength spacing is used to analyze its transmission characteristics. The simulation results show that the resonant wavelength in the horizontal channels shifts when the sectional size of the waveguide core, the buffer layer thickness between the waveguide core and electrode, electrode thickness, and coupling gap between the microring and channel are 1.5 × 1.5 μ m 2 , 2.0 μm, 0.05 μm, and 0.1μm, respectively; this shift also occurs when the switching voltage changes from 0 to 21.3V. Thus, resonance wavelength conversion with 0.8-nm wavelength spacing can be achieved in the same horizontal channel.
