Query: Bending of solitonic beams modelled by coupled KMN equation in optical
  birefringent fibers   The dynamics of (2 + 1) dimensional optical solitonic beams in birefringent
fibers without four wave mixing terms are considered using the recently
introduced coupled Kundu Mukherjee Naskar (KMN) equation. The arbitrary bending
of solitonic beams in this coupled optical fiber system has been discussed with
various two and three dimensional plots. Such analytical results on the bending
of optical pulse may pave new directions of research in this field.
