Abstract We have studied the squeezing of the two-mode radiation fields in a nonlinear optical fiber with gain, The coupling nonlinear Schr$\ddot{\rm o}$dinger equations corresponding to the circularly polarized radiation fields with gain are derived by means of the method of path integrals. The minimized power spectra of the quantum noise of these fields are obtained with a first-order perturbation approximation in the frequency domain. Detailed numerical analyses of the results are performed and presented graphically, taking zero-dispersion, normal and anomalous dispersion into account.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
