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.
