Abstract

We use fine-detuning of pump wavelengths to adjust the tap phases in a complex-coefficient optical tapped-delayline that utilizes conversion/ dispersion-based delays and nonlinear wave mixing. Full 2π phase tuning is demonstrated by detuning the frequency of laser pumps by <20 GHz, which shows close agreement with theory.
