| Abstract: The various technologies presented herein relate to utilizing photons at
respective idler and signal frequencies to facilitate generation of
photons at a pump frequency. A strong pump field can be applied at the
.omega..sub.i and the .omega..sub.s frequencies, with the generated idler
and signal pulses being utilized to generate a photon pair at the
.omega..sub.p frequency. Further, the idler pump power can be increased
relative to the signal pump power such that the pump power
P.sub.i>pump power P.sub.s. Such reversed operation (e.g.,
.omega..sub.i+.omega..sub.s.fwdarw..omega..sub.p1+.omega..sub.p2) can
minimize and/or negate Raman scattering effects. By complying with an
energy conservation requirement, the .omega..sub.i and .omega..sub.s
photons interacting with the material through the four-wave mixing
process facilitates the entanglement of the .omega..sub.p1 and
.omega..sub.p2 photons. The .omega..sub.i and .omega..sub.s photons can
be respectively formed in different length waveguides with a delay
utilized to facilitate common timing between the .omega..sub.i and
.omega..sub.s photons. |
