Coherent Manipulation of Optical Soliton in Four Level N-type Atomic Medium

Optical solitons are controlled and modified in a four level N-type atomic medium under the effect of cross Kerr nonlinearity. Significant control over optical solitons are reported with variation of driving fields and system parameters. The single and mixed types optical solitons are controlled for the first time with strength of applied driving fields in the medium. Single dark and bright optical solitons are achieved by fixing Rabi frequencies, detuning and phase of applied driving fields. The multi-peakon and periodic type optical solitons are also modified with strength of applied driving fields. Further more the mixed-types of optical solitons including dark-peakon, breather-periodic, multi-peakon-breather and multi-peakon-breather-periodic types optical solitons are investigated with the variation of control fields Rabi frequencies, detunings and decay rates. The modified single and mixed types optical solitons have potential application in soliton radar technology and sensors as well as communication technologies.
