Light-enhanced electro-optic spectral tuning in annealed proton-exchanged periodically poled lithium niobate channel waveguides

Abstract

We report the observation of light-enhanced electro-optic spectral tuning in annealed proton-exchanged, asymmetric domain-duty-cycle periodically poled lithium niobate (PPLN) channel waveguides for second-harmonic generation. The spectral tuning rate was increased rapidly from $0.07\mathrm{nm}∕(\mathrm{kV}∕\mathrm{mm})$ to a saturated value of $0.32\mathrm{nm}∕(\mathrm{kV}∕\mathrm{mm})$ in a 30%/70% domain-duty-cycle PPLN waveguide when the fundamental pump power near $1534\mathrm{nm}$ was increased from 0.6 to $46\mathrm{mW}$. The second-harmonic laser power at $767\mathrm{nm}$ was identified to be the source enhancing the spectral tuning.
