Generation of high-modulation-index RF analog signals using a silicon microring resonator

摘要

We propose a compact silicon microring-based analog modulator for generation of 10-GHz sub-octave analog signals, which exhibit high optical modulation-index of up to 46% and carrier-to-noise ratio (CNR) of 57 dB. In fiber transmission, the CNR can be improved further by 10 dB with chromatic dispersion.
