中文摘要	novel compact design for 4-channel soi-based reconfigurable optical add/drop multiplexer using microring resonators is presented and analyzed. microring resonators have two important attributes as a key new technology for future optical communications, namely functionality and compactness. functionality refers to the fact that a wide range of desirable filter characteristics can be synthesized by coupling multiple rings. compactness refers the fact that ring resonators with radii about 30 mu m can lead to large scale integration of devices with densities on the order of 10(4) similar to 10(5) devices per square centimeter. a 4-channel reconfigurable optical add/drop multiplexer comprises a grid-like array of ridge waveguides which perpendicularly cross through each other. soi-based resonators consisted of multiple rings at each of the cross-grid nodes serve as the wavelength selective switch, and they can switch an optical signal between two ports by means of tuning refractive index of one of the rings. the thermo-optic coefficient of silicon is 1.86x 10(-4) /k. thus a temperature rise of 27k will increase the refractive index by 5 x 10(-3), which is enough to cause the switching of our designed microring resonators. the thermo-optic effect is used to suppress the resonator power transfer, rather than to promote loss. thus, the input signal only suffers small attenuation and simultaneously low crosstalk can be achieved by using multiple rings.
