Soliton squeezing at GHz rate in a Sagnac loop

C. X. Yu, H. A. Haus, Erich P. Ippen

Published Aug 1, 2001• 4 citations
OpenAlex

Abstract

We demonstrate the first all-fiber squeezing experiment at room temperature. A record 6.1+/-0.2 dB of noise reduction below shot noise has been obtained without stabilization. When loss is taken into account, /spl sim/11 dB of squeezing is inferred.

Soliton squeezing at the gigahertz rate in a Sagnac loop

C. X. Yu, H. A. Haus, Erich P. Ippen

We demonstrate what is to our knowledge the first all-fiber squeezing experiment. A balanced Sagnac loop is used, and a record 6.1+/-0.2dB of noise reduction below shot noise has been obtained without stabilization. A gigahertz Er-doped fiber laser and a high-power double-clad Er-Yb amplifier have been developed to suppress guided acoustic-wave Brillouin scattering and to make possible the all-fiber configuration.

Amplitude Soliton Squeezing Using an Asymmetric Sagnac Fiber Loop

Dmitriy Krylov, K. Bergman

We experimentally demonstrate a new scheme for generating amplitude squeezed solitons in an asymmetric fiber Sagnac loop. We measure by direct detection a 5.7±0.1 dB (73%) and, with corrections for linear losses 6.2±0.1 dB (76%), reduction in the photon number fluctuations below the shot noise level. The same scheme is also shown to generate a significant classical noise reduction and is limited by Raman effects in fiber. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.

Amplitude-squeezed solitons from an asymmetric fiber interferometer

Dmitriy Krylov, K. Bergman

We experimentally demonstrate a new scheme for generating amplitude-squeezed solitons in an asymmetric fiber Sagnac loop. We measure by direct detection what is to our knowledge a record reduction of 5.7+/-0.1 dB (73%) and, with corrections for linear losses, 6.2+/-0.1 dB (76%) in the photon-number fluctuations below the shot-noise level. The same scheme is also shown to generate significant classical noise reduction and is limited by Raman effects in fiber.

Photon-Number Squeezed Solitons from an Asymmetric Fiber-Optic Sagnac Interferometer

Stefan Schmitt, Joachim Hans Ficker, Max Wolff +3 more

Direct photon-number squeezing is demonstrated, for the first time to our knowledge, in a nonlinear fiber-optic interferometer. Launching 126-fs solitons into a highly asymmetric Sagnac loop, the maximum photocurrent noise reduction was $3.9\ifmmode\pm\else\textpm\fi{}0.2\mathrm{dB}$ below shot noise, corresponding to $6.0\ifmmode\pm\else\textpm\fi{}0.9\mathrm{dB}$, when corrected for linear losses. The loop is a model system for squeezing generated by the interference of two pulses after nonlinear propagation through a fiber.

Squeezed optical solitons

M. Rosenbluh, Robert M. Shelby

We have experimentally demonstrated the squeezing of optical solitons, resulting in a detected photocurrent noise power (32\ifmmode\pm\else\textpm\fi{}3)% (1.7 dB) below the shot-noise limit over a broadband of frequencies. The squeezing is accomplished using the Kerr nonlinearity of a polarization-preserving single-mode optical fiber at liquid-nitrogen temperature. Squeezed solitons, 1.1 dB below the shot-noise limit, were observed at room temperature.
