Surface nonlinear light generation in microresonators

The authors have experimentally demonstrated phase matched SHG in the whispering gallery modes of a micro-sphere due to a surface nonlinearity. The nonlinear material used is down to a single monolayer of nonlinear molecules covering the sphere surface in the appropriate configuration to reach phase...

Description
Summary:The authors have experimentally demonstrated phase matched SHG in the whispering gallery modes of a micro-sphere due to a surface nonlinearity. The nonlinear material used is down to a single monolayer of nonlinear molecules covering the sphere surface in the appropriate configuration to reach phase matching. This system, apart from fundamental interest, has promising applications in sensor technology.
