In this paper, we describe an all-fiber nonlinear interferometer based on four-wave mixing in highly nonlinear fiber. Our configuration realizes phase-sensitive interference with 97% peak visibility and >90% visibility over a broad 554 GHz optical band. By comparing the output noise power to the shot-noise level, we confirm noise cancellation at dark interference fringes, as required for quantum-enhanced sensitivity. Finally, our device extends nonlinear interferometry to the important platform of highly nonlinear optical fiber and could find applications in a variety of fiber-based sensors.
