Continuous wave, low-noise parametric amplification in monolithic silicon-nitride waveguides

Abstract

Parametric amplifiers, relying on a nonlinear material to create amplification, are promising as they can amplify light without generating excess noise. Here, we will discuss our recent demonstration of continuous wave parametric amplification, in both phase-insensitive and phase-sensitive mode, based on the 3rd order nonlinearity in a monolithic, compact, spiral-shaped silicon-nitride waveguide. We observe an on-chip gain of up to about 10 dB with a noise figure of 1.2 dB, i.e., well below the conventional amplifier quantum-limited noise figure of 3 dB. Our results show the potential for realizing continuous-wave parametric amplification that can enable applications in optical communications, signal processing and quantum optics across a wide range of frequencies.
