Paper Abstract
In the present work, a PT-symmetric closed-form quadrimer waveguides system has been considered. We observe the
saturation of the optical powers in the gain-guides in nonlinear regime under the coupling scheme considered.
Moreover, we also find that accumulation of optical powers in the g-r parametric space (‘g’ is the gain/loss parameter, ‘r’
nonlinearity co-efficient) in the different waveguides significantly depends on the nature (i.e. focusing or defocusing)
and the strength of nonlinearity and gain/loss profile. The potential applications of this quadrimer system might be in
generating high constant-power optical sources.
