Abstract
Theoretical analysis and numerical results for typical examples are presented for three-layer planar waveguides with nonlinear claddings to find the appropriate structures in which the core electric field can become uniform at appropriate optical power while the cladding fields decay exponentially. It is shown that there are five kinds of such structures. The electric field profiles are plotted for the five typical examples. We notify that the occurrence of uniform field in a waveguide core may perhaps have prospective applications in waveguide, opto-electronic and photonic devices.
