WebMar 30, 2024 · Using this waveguide, we observe CW 6.3-dB squeezing at 20-MHz sideband by balanced homodyne detection. This is the first realization of CW squeezing … WebOptical fiber communications typically operate in a wavelength region corresponding to one of the following “telecom windows” (or communication bands):. The first window at 800–900 nm was originally used. GaAs/AlGaAs-based laser diodes and light-emitting diodes (LEDs) served as transmitters, and silicon photodiodes were suitable for the …

WebBy accounting for the overall detection efficiency of 60%, we infer that the generated on-chip squeezing factor can be tuned from 0.9 ± 0.4 dB to 3.9 ± 0.3 dB. The measured and inferred squeezing levels match reasonably well with the predictions of Eq. 1 for ηd = 60% and ηd = 100% respectively. Weboptics on lithium niobate and off-the-shelf telecom and nonlinear components. The realised photonic circuit integrates on-chip the squeezing generation and the optical coupler of the homodyne interferometer. The squeezed light generated at telecom wavelength exhibits a noise compression of −2.00 ± 0.05 dB for a pump power of 40 mW.
