A simple and fast frequency domain analysis method for calculating the frequency response and linearity of electro-optic microring modulators
Abstract
A fast and simple frequency domain method is introduced for the analysis of microring modulator response using the Jacobi Anger expansion method. Resonance frequency modulated microring (FMMR) modulators and coupling modulated microring modulators (CMMR) are analyzed using this method. The linearity of these modulators is analyzed. The third order intercept point (IP3) is calculated for CMMR devices and compared to Mach Zehnder interferometer (MZI) modulator devices. It is shown that CMMR devices can achieve a 12dB higher IP3 compared to MZI devices. CMMR devices have high second order nonlinearity, while MZI devices second order nonlinearity is zero. A novel geometry based on dual CMMR modulators is introduced to improve the second order nonlinearity of CMMR modulators.
