An interferometer with double loops based on a planar 3 × 3 coupler is proposed.The main factors that cause the instability of the polarization state are obtai
We investigate modulation instability (MI) in the presence of a monochromatic spectrum and on the background of a broadband amplified spontaneous emission spect
Discharges in planar-type overdense plasmas caused by resonant excitation of surface plasmon polaritons(SPPs)are presented.The spatio-temporal evolution of surf
