Squeezed light generation by four-wave mixing in semiconductors
We have generated pulsed quadrature squeezed light by self-phase modulation (SPM) in ZnS and cross-phase modulation (XPM) in cubic ZnSe at photon energies slightly less than half the band gap in both materials. 40% squeezing at 780nm was obtained in the SPM experiment, while the XPM geometry produce...

| Summary: | We have generated pulsed quadrature squeezed light by self-phase modulation (SPM) in ZnS and cross-phase modulation (XPM) in cubic ZnSe at photon energies slightly less than half the band gap in both materials. 40% squeezing at 780nm was obtained in the SPM experiment, while the XPM geometry produced 14% squeezing at 960nm. The smaller noise reduction for XPM squeezing is related to the smaller off-diagonal susceptibility that produces the nonlinear mixing. |
