Soliton Squeezing in Microstructure Fiber

Abstract
We experimentally demonstrate the generation of amplitude-squeezed light by means of soliton self-phase modulation in a microstructure fiber. By injecting 200 fs pulses at 1550 nm into the fiber we observe the formation of solitons. Subsequent mixing of the solitons with weak pulses allows us to measure sub-shot-noise amplitude fluctuations; a maximum noise reduction of 2.7 dB is measured without correction for detection losses. The dependence of the noise reduction on various system parameters is studied in detail and the results are compared with those of a similar experiment carried out in standard polarization-maintaining fiber.
