Nonlinear Coherent Perfect Absorption
K. Nireekshan Reddy, S. Dutta Gupta
We review some of the recent concepts and their realization exploiting the perfect destructive interference of light in micro and nano structures. One refers to optical structures…

Cavity controlled spectral singularity
K. Nireekshan Reddy, S. Dutta Gupta
We study theoretically a PT-symmetric saturable balanced gain-loss system in a ring cavity configuration. The saturable gain and loss are modeled by two-level medium with or withou…

Gap solitons with null-scattering
K. Nireekshan Reddy, S. Dutta Gupta
We study excitation of gap solitons under the conditions of coherent perfect absorption (CPA). Our system consists of a symmetric periodic structure with alternating Kerr nonlinear…
