Abstract
We present that the linearity of silicon ring modulators in microwave photonics links can be improved by manipulating the quality factor in the cavity. By reducing Q factors of silicon ring modulators from 11000 to 5880 and tuning the operation wavelength for modulation, the measured Spurious-Free Dynamic Ranges of the third-order intermodulation distortion are improved from 98.5 dB·Hz2/3 to 104.3 dB·Hz2/3 and from 90.6 dB·Hz2/3 to 94.7 dB·Hz2/3 at 1 GHz and 10 GHz, respectively.
