title: Continuous wave photon pair generation in silicon-on-insultator waveguides and ring resonators and erratum: comment.
abstract: We consider the generation of photon pairs by spontaneous four-wave mixing in ring resonators, as described by Clemmen et al. in Opt. Express17, 16558 (2009). We show that the theoretical limit predicted for the generation rate in their Erratum-Opt. Express 18, 14107 (2010)-is far too large due to an incorrect definition of a field enhancement factor.
