Photon pair generation via down-conversion in III-V semiconductor microrings: modal dispersion and quasi-phase matching
We explore how III-V semiconductor microring resonators can efficiently
generate photon pairs and squeezed vacuum states via spontaneous parametric
down-conversion by utilizing their built-in quasi phase matching and modal
dispersion. We present an analytic expression for the biphoton wave function of
photon pairs generated by weak pump pulses, and characterize the squeezed
states that result under stronger pumping conditions. Our model includes loss,
and captures the statistics of the scattered photons. A detailed sample
calculation shows that for low pump powers conversion efficiencies of
10$^{-5}$, corresponding to a rate of 39 MHz for a pump power of 1 $\mu$W, are
attainable for rudimentary structures such as a simple microring coupled to a
waveguide, in both the continuous wave and pulsed excitation regimes. Our
results suggest that high levels of squeezing and pump depletion are
attainable, possibly leading to the deterministic generation of non-Gaussian
states
