Figure: Nonclassical hybrid passive–active power stabilization enables milliwatt-level bright squeezing across kHz–MHz band. a, Simplified schematic of squeezed light generation integrating multiple noise suppression techniques. b, Relationship between the laser power and relative shot noise. c, Measurement results of bright squeezed light at 1 mW with nonclassical hybrid passive-active stabilizations. All measurements were performed using a spectrum analyzer (R&S FSW) at two frequency bands, 1-100 kHz and 100 kHz-1 MHz, with a resolution bandwidth (RBW) of 100 Hz and a video bandwidth (VBW) of 10 Hz.
