Resonant Squeezed Light via Four-Wave Mixing

Generating narrowband two-mode and single-mode squeezed light resonant with ⁸⁷Rb

Summary

Generated two-mode squeezed light resonant with ⁸⁷Rb transitions using FWM in ⁸⁵Rb vapor — enabling quantum-enhanced atomic sensing.

Challenge

Off-resonant squeezing cannot directly enhance atomic sensors; resonant generation requires navigating competing absorption losses.

Contribution

Demonstrated singly- and doubly-resonant two-mode squeezing; implemented feedforward to transfer squeezing to single mode.

Outcome

Achieved −6.3 dB resonant squeezing; −2.0 dB single-mode squeezing — first demonstration for ⁸⁷Rb.
