Superpositions of squeezed coherent states: Properties and generation

The s-parameterized charactristic function for the superposition of squeeze d coherent states (SCS's) is given. The s-parameterized distribution functi ons for the superposition of SCS's are investigated. Various moments are ca lculated by using this charactristic function. The Glauber second-order coh erence function is calculated. The photon number distribution of the superp osition of SCS's studied. Analytical and numerical results for the quadratu re component distributions for the superposition of a pair of SCS's are pre sented. The phase distribution calculated from the integration of s-paramet erized distribution function over the phase space. A generation scheme is d iscussed.
