Abstract

We experimentally prove two novel techniques which solve issues in photon-number squeezed pulse generation with ultrafast nonlinear fiber optics: one is with Er-doped fiber laser source, and the other is with a normal dispersion fiber at 800 nm. We successfully obtaine photon number squeezing for each case.

Generation of photon-number squeezed states with a fiber-optic symmetric interferometer

Aruto Hosaka, Kenichi Hirosawa, Ryota Sawada +1 more

We numerically and experimentally demonstrate photon-number squeezed state generation with a symmetric fiber interferometer in an 800-nm wavelength and compared with an asymmetric fiber interferometer, although photon-number squeezed pulses have been generated only with asymmetric interferometers. Even though we obtain -1.0dB squeezing with an asymmetric fiber interferometer, since perfect spectral phase and intensity matching between displacement and signal pulses are achieved with a symmetric fiber interferometer, we obtain better squeezing of -3.1dB. We also numerically calculate and clarify this scheme's usefulness at a 1.55-μm wavelength.

Photon Number Squeezing of Ultrabroadband Laser Pulses Generated by Microstructure Fibers

Kenichi Hirosawa, Hiroto Furumochi, Atsushi Tada +3 more

To the best of our knowledge, we demonstrate for the first time the generation of photon number squeezing by spectral filtering for ultrabroadband light generated by microstructure fibers at 800 nm. A maximum squeezing of 4.6 dB is observed, corresponding to 10.3 dB after correcting for detection losses. We numerically analyzed the quantum dynamics of ultrashort laser pulse propagation through optical fibers by solving a nonlinear quantum Schrödinger equation that included Raman scattering, especially for the quantum correlation of photon number fluctuation among frequency modes in broadband pulses.
