Optimized microfiber-based third-harmonic generation with adaptive control of phase mismatch

Optimized microfiber-based third-harmonic generation with adaptive control of phase mismatch

An effective approach is presented to improve intermodal third-harmonic generation in microfibers. It is demonstrated that structure-independent incident pump power could be utilized, via its effect on nonlinear phase modulations, to compensate for the phase mismatch caused by diameter deviation. The output harmonic of a fabricated microfiber can be optimized adaptively; thus, efficient third-harmonic generation with efficiency reaching several percent could realistically be achieved.

Abstract

An effective approach is presented to improve intermodal third-harmonic generation in microfibers. It is demonstrated that structure-independent incident pump power could be utilized, via its effect on nonlinear phase modulations, to compensate for the phase mismatch caused by diameter deviation. The output harmonic of a fabricated microfiber can be optimized adaptively; thus, efficient third-harmonic generation with efficiency reaching several percent could realistically be achieved.
