Analysis of resonance enhancement in defect-mediated silicon micro-ring photodiodes operating at 1550 nm

The resonant defect-enhanced photodiode has received recent attention for its potential use in silicon photonic applications such as wavelength division multiplexing (WDM). Here, we analyze the nature of the resonant enhancement in micro-ring photodiodes by exploring the roles of defect content and...
