A Simulation of Pulsed Squeezing in Short Optical Fiber Loop Mirror

Quadrature squeezed light generation with picosecond optical pulses in a fiber loop mirror whose length is as short as 2 m is analyzed through the computer simulation. When the pulse width is 10 ps, the evolution of the squeezing parameter is almost independent of the second order dispersion β 2 in the region of |β 2| <15 ps2/km. When the pulse width is 1 ps, enhancement of the squeezing in the normal dispersion regime occurs. On the other hand, the squeezing in the anomalous dispersion regime is obviously degraded. These results are due to the pulse broadening or narrowing effects. When the pulse width is 1 ps and the peak power is 1 kW, the maximum squeezing at 2.2 m is 8.2 dB for β 2 = 15 ps2/km.
