Generation of Intensity Difference Squeezed State of Light at Optical Fiber Communication Wavelength

Dependence of the squeezing and anti-squeezing factors of bright squeezed light on the seed beam power and pump beam noise

“…Since the first experimental demonstration of squeezed states based on the OPO succeeded in 1986 [16], intensive researches are carried out to increase the squeezing factor in the last thirty years [17][18][19][20][21][22][23][24][25][26]. Under the motivation of gravitational waves detection, a 10 dB squeezed vacuum state was detected for the first time at the University of Hanover in 2007 [20].…”
