Abstract
A novel wavelength selective 2x2 switch based on two microring resonators is proposed. The device consists of two intersecting channel waveguides with each of the two rings coupled to both waveguides. Depending on the control voltage the light of selected wavelength either can propagate through the straight waveguide or can be coupled to one of the rings and from the ring couple to the perpendicular output. Therefore every ring can independently switch one wavelength from any input to the perpendicular output. This wavelength selective switching adds to the traditional switch functionality. Theoretical calculations were carried out to determine optimum parameters of the switch and soft-lithography was used for implementation. Being fabricated from the latest electro-optical polymers this device can provide very high switching speed and low operation voltage.
