摘要：
By using overlapping-imaging characteristic of the multimode interference (MMI) and the area modulation method, this paper presents a three-wavelength 3x3 rearrangeable switch, which consists of the two cascaded building blocks: a 2x2 tunable splitter and a full shuffle 1 x 3 switch with only one compound modulation region. Its operation characteristics are analyzed by utilizing 2-D BPM simulation. The simulated extinction ratio is higher than 30dB for all operating wavelengths 1545 nm, 1550 nm and 1555 nm. Good 3-D performances can be expected after optimization and improved fabrication.
