Analysis of Silicon Photonic Microringassisted WDM IQ Modulator

WDM IQ modulator with silicon photonic microrings is analyzed using a rigorous numerical model. The under-coupled four-microrings-per-wavelength configuration is revealed to incur only 1dB penalty for QPSK format, offering enhanced flexibility in designing the microrings.
