The study demonstrates the potential of nanophotonics for continuous-wave parametric amplification, enabling applications in various fields such as optical communications, signal processing, and quantum optics.
Optical amplifiers are essential in numerous photonic applications. Parametric amplifiers, relying on a nonlinear material to demonstrate amplification based on the third-order nonlinearity in a single chip while, in addition, reporting a noise figure significantly below the conventional quantum limit when operated in phase-sensitive mode. Our results show the potential of nanophotonics for realizing continuous-wave parametric amplification that can enable applications in optical communications, signal processing, and quantum optics across a wide range of frequencies.
