The effect of scattering loss on connections between classical and quantum processes in second-order nonlinear waveguides
L. G. Helt, M. J. Steel
We show that a useful connection exists between spontaneous parametric downconversion (SPDC) and sum frequency generation in nonlinear optical waveguides with arbitrary scattering…
Bi-photon spectral correlation measurements from a silicon nanowire in the quantum and classical regimes
Iman Jizan, L. G. Helt, Chunle Xiong +7
The growing requirement for photon pairs with specific spectral correlations in quantum optics experiments has created a demand for fast, high resolution and accurate source charac…
Tuneable quantum interference in a 3D integrated circuit
Zachary Chaboyer, Thomas Meany, L. G. Helt +2
Integrated photonics promises solutions to questions of stability, complexity, and size in quantum optics. Advances in tunable and non-planar integrated platforms, such laser-inscr…
Spontaneous parametric downconversion in waveguides: What's loss got to do with it?
L. G. Helt, J. E. Sipe, M. J. Steel
We derive frequency correlation and exit probability expressions for photons generated via spontaneous parametric downconversion (SPDC) in nonlinear waveguides that exhibit linear…
