Microwave Magnetic Envelope Solitons in Yttrium
Iron Garnet Thin Films - Parallels and Contrasts
to Optical Solitons
Microwave magnetic envelope (MME) solitons in low loss yttrium
iron garnet thin films allow one to test the nonlinear effects
which govern optical solitons on a scale for which phase as well
as amplitude can be measured directly and in a system for which
the nonlinear and dispersion parameters can be tuned by changing
the direction and size of the magnetic field, the operating point
frequency, and the propagation direction. One can tune the dispersion
and nonlinear parameters to produce bright and dark solitons,
trains of solitons, and higher order solitons in a controlled and
quantitative fashion. This paper will first consider the parallels
and contrasts between optical solitons in fiber optic media
and MME solitons in magnetic films. It will then review recent
results on MME soliton amplitude and phase profiles, threshold and
velocity characteristics, direct Brillouin light scattering
soliton observations and analyses, and dark solitons.
