A proposal for highly tunable optical parametric oscillation in silicon micro-resonators [PDF]
, 2008 We propose a novel scheme for continuous-wave pumped optical parametric oscillation (OPO) inside silicon micro-resonators. The proposed scheme not only requires a relative low lasing threshold, but also exhibits extremely broad tunability extending from ...
