Abstract :
The design and analysis of series-coupled double ring resonators with multiple quantum wells as the light guiding medium for wavelength switching applications will be presented. Switching is realized by changing the absorption of the rings. The output intensity at the output port and drop port of the resonator is calculated as a function of device geometry. A theoretical model for the switch which incorporates the change in absorption coefficient due to the applied electric field is presented. It is found that the switching characteristics of the device strongly depend on quantum well and material parameters.
