Circumventing spontaneous Raman noise in a correlated photon pair source

Circumventing spontaneous Raman noise in a correlated photon pair source

We propose a dual-pump third-order nonlinear scheme for producing pairs of correlated photons that is less susceptible to Raman noise than typical spontaneous four-wave mixing (SFWM) methods. Beginning with the full multimode Hamiltonian, we derive a general expression for the joint spectral amplitu...
