Abstract

Significant progress has been recently achieved in producing amplitude-squeezed optical soli-ton pulses in a new experimental scheme. This scheme, originally proposed¹ and later generalized by M. J. Werner,² is based on interference of optical fields and is potentially capable of producing large squeezing levels in excess of 10 dB. In an experimental demonstration of this scheme the authors have recently reported directly observing 5.7-dB (6.2 dB correcting for losses) in the photon-number fluctuations below the shot-noise level with 180-fs, high-energy, soliton pulses centered at 1550 nm in a highly asymmetric Sagnac interferometer geometry.³
