Abstract
Based on Mach-Zehnder interferometer (MZI) structure, a 2Â ÃÂ 2 optical switch is fabricated on SOI wafer. Modulation of the refractive index of MZI arms is achieved through free carriers plasma dispersion effect of silicon. The device presents an insertion loss as low as 3.44Â dB and a response time as small as 300Â ns. The crosstalk and extinction ratio are â15.54 and 14.9Â dB, respectively. Detailed analysis and explanation of the operating behaviors are also presented.
