Abstract
A tunable parametric mixer comprising a pump laser, a nonlinear waveguide, and a refractive index tuner. The pump laser is configured to generate pump photons. The nonlinear waveguide comprises a cladding and a core. The core is made of nonlinear optical material and the cladding in made of a material with a tunable index of refraction. The nonlinear waveguide is configured to convert the pump photons into signal and idler photons. The refractive index tuner is configured to change the refractive index of the cladding to dynamically tune the dispersion properties of the nonlinear waveguide in order to alter a spectral location of a gain band of the parametric mixer.
