摘要：

We investigate the performances of a silicon PN-junction Mach-Zehnder modulator for analog application. The slope efficiency and spurious-free dynamic range (SFDR) of such a modulator upon carrier depletion and carrier injection effects are characterized and compared. Input RF frequency-dependence measurements show that the depletion-type modulator is usually with similar to 20 dB(.)Hz(2/3) higher SFDR comparing to the injection-type modulator, yet with an order-of-magnitude lower slope efficiency. For the depletion-type and injection-type modulators, the measured maximum SFDRs are respectively similar to 95 dB(.)Hz(2/3) and 75 dB(.)Hz(2/3), with maximum slope efficiency of 0.3 V-1 and 8 V-1. We numerically model the SFDR by using the experimentally extracted effective refractive index change, which shows good agreement with the measurements. (C) 2013 Optical Society of America
