A study of multiparameter families of walking solitons has been
done in collaboration with Drs.Mihalache and Mazilu (Institute
of atomic physics, Bucharest, Romania). The results on soliton
stability in systems with gain and loss in the normal dispersion
regime have been obtained in collaboration with Dr. Wabnitz
(Univ. Bourgogne, Dijon, France).
A number of important results related to solitons in systems with
higher order dispersion have been obtained in collaboration
with Dr.Karlsson, (Chalmers Univ.of Technology, Göteborg, Sweden).
Theoretical results on short pulse propagation in birefringent fibers were
obtained in collaboration with Prof. Andersen (University of
Iowa, USA). The research on incoherent solitons in media with
saturable nonlinearity is continuing in collaboration with Dr.
Litchinitser and Prof. Agarwal (Inst.of Optics, Rochester, USA).
A study of polarization locking effects is in progress in collaboration
with a group of scientists: Dr.Knox and Dr.Collings (Bell Labs,
Lucent Technologies), Dr.Cundiff (JILA, Univ. of Colorado, Boulder)
