Effect of Detuning the Group Velocities of Optical Harmonics on the Reflection and Transmission of Radiation in an Active Periodic Medium

The authors study the effect detuning between the group velocities of two optical harmonics has on the reflection and transmission of radiation in a layered active quadratically nonlinear medium. The reflectance and transmittance at the fundamental and doubled frequencies are determined via numerical modeling. The soliton nature of energy transfer inside a medium is demonstrated.
